Tapered amplifier (TA) diodes combine the "best of both worlds": They amplify laser radiation into a nearly diffraction limited beam to powers that would destroy the facets of normal laser diodes. At the same time the spectral properties of the master laser are preserved. TOPTICA offers TA chips separately, but also integrates them into convenient laser systems (TA pro and BoosTA)

Distributed feedback (DFB) laser diodes feature a grating structure within the semiconductor and thus operate in both longitudinal and transverse single mode. Tuning is achieved by modulating either the laser current or the chip temperature. Mode-hop free tuning is maintained over several hundred GHz. Applications include alkaline spectroscopy, laser cooling, gas detection and the generation of tunable cw terahertz radiation.

TOPTICAs DigiLock 110 is the versatile solution for laser control, stabilization, characterization & analysis. Its digital nature makes it easy to use, flexible and intelligent. The FPGA based hardware allows for high bandwidth and flexibility, and with its clever software one has the overview, but can go into every tiny detail if need be.

The DLC pro Lock is a software license that enables a number of features on a specific DLC pro. These allow to control the frequency of a laser for example by using a saturated absorption spectroscopy setup with a reference cell. This most popular example of frequency typically uses a modulation of the laser frequency, a de-modulation (Lock-In) for creation of the error signal and PID regulators for the generation of the error signal. All this may be achieved with a DLC pro control without further electronic modules.

The PID 110 is a proportional-integral-differential regulator for frequency stabilization of tunable diode lasers (DL pro, DFB pro). It accomplishes side-of-fringe locking to the slope of an atomic line or a cavity transmission peak. The module works both for HV (piezo actuators) and LV (laser current) control tasks. Users can adjust all relevant parameters, including P, I and D contributions, set point and regulator output range.

The Pound-Drever-Hall detector PDD 110/F serves to lock a diode laser to a maximum absorption or transmission of a reference medium (e.g. an optical resonator). The PDD 110/F features an internal HF modulation source for modulating the diode laser frequency. The signal from the reference is detected and demodulated phase sensitively to produce a high bandwidth dispersive error signal that can be used to lock the laser using a PID controller.

The Pound-Drever-Hall detector PDH is a built-in module of the DLC pro and serves to lock a diode laser to a maximum absorption or transmission of a reference medium (e.g. an optical resonator). The PDH features an internal HF modulation source for modulating the diode laser frequency. The signal from the reference is detected and demodulated phase sensitively to produce a high bandwidth dispersive error signal that can be used to lock the laser using a PID controller.

The Fast Analog Linewidth Control (FALC 110) is a module for advanced laser frequency stabilization tasks, such as linewidth reduction and high-bandwidth frequency locking. Due to an optimized circuit layout, the -3 dB bandwidth of the fastest signal path reaches 100 MHz. The Mixing FALC (mFALC) additionally comprises an analog mixer for phase detection, and is designed for fast phase locking of two lasers to an external RF reference.

The DLC pro is a platform driving all tunable diode lasers of TOPTICA: One controller for all wavelengths. The performance of diode lasers is largely determined by its controller. The DLC pro is the first diode laser controller based on a digital foundation, which is essential to obtain the best performance on all key parameters: Low current noise for narrow laser linewidths, excellent temperature control for stable operation and precise piezo control for frequency tuning.

The revolutionary TOPO by TOPTICA stands alone as the only fully automated, continuous-wave, singly-resonant optical parametric oscillator laser source on the market. High resolution spectroscopy across 1.45 – 4.0 µm (2500 – 6900 cm-1) has never been easier. TOPTICA’s unique optical design enables broadly tunable laser light. No module or mirror exchange is necessary. Additionally, the all-digital control electronics enable hands-free coarse tuning, and frequency locking. A wide mode-hop-free tuning range up to 300 GHz (10 cm-1) enables visibility of full spectroscopic signatures. Simultaneously, the TOPO maintains a narrow linewidth (2 MHz, 1·10-5 cm-1) giving a solution that reveals narrow atomic and molecular features.

The TA-FHG pro is a tunable, diode-based laser source in the deep UV spectral range. The system consists of an external cavity diode laser, a high power semiconductor amplifier (TA), and two cascaded second harmonic generation stages (SHG pro). Alternatively, it can be equipped with a fiber amplifier (FA) or Raman fiber amplifier (RFA). It provides tunable laser radiation for spectroscopy, laser cooling, holography and interferometry.

The SHG pro is the device of choice if existing lasers are to be frequency doubled. Designed in TOPTICA’s pro technology, it unites highly stable performance and convenient operation. Mirror and crystal holders can be adjusted without opening the resonator cover. A wide range of non-linear crystals covers SHG wavelengths from 190 to 800 nm. TOPTICA offers competent support for adapting the unit to customer requirements.

The BoosTA is a compact and economical optical amplifier. Just couple light into it, and it amplifies it up to a factor 100. The spectral properties of the master laser are preserved. The BoosTA includes computer controlled integrated electronics, and all optics for accepting a collimated and linearly polarized input beam. Custom optics and good thermal management guarantee best performance.

Distributed feedback (DFB) lasers unite wide tunability and high output power. The frequency-selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures continuous single-frequency operation. Due to the absence of alignment-sensitive components, DFB lasers exhibit an exceptional stability and reliability. The lasers work under the most adverse environmental conditions – even in the Arctic or in airborne experiments.

Our DL pro is the ultimate tunable diode laser. Its revolutionary mechanical design allows for both easy operation and extreme stability at the same time. It offers highest output powers, and optimized mode-hop-free tuning with a perfectly positioned virtual pivot point for the grating movement (Patents: DE 10 2007 028 499 and US 7970024). Together with the digital control DLC pro controller it shows unrivalled linewidth and drift – with the most comfortable and intuitive user interface. Also available with the economic SYST laser electronics. A software license may be purchased to enable frequency-locking features.

The CTL is the ultimate choice when looking for a laser that is widely and continuously tunable without any mode-hops. It has high power, a narrow linewidth and low drift. Scans can be performed with highest resolution. Mode-hops are prevented by an innovative opto-mechanical design (patent US9960569B2) together with an active feedback loop called SMILE (Single Mode Intelligent Loop Engine) that keeps the laser on the same mode at all times. With the fully digital, low noise and drift DLC pro controller, the CTL laser is easy to use and operate via touch-screen and knobs as well as via remote PC GUI and command language (Python SDK). With firmware 2.0.3 (free updates available), DLC CTL now includes a test system for characterizing components or recording spectra.

The MDL pro combines up to four narrow-linewidth tunable diode lasers in one compact sub-rack. This solves many problems of modern atomic optics: It simplifies complex operations because all integrated lasers are controlled using only one unified interface. Furthermore, it clears optical tables and stows away the lasers in a 19" standard subrack. This enables researchers to focus on their experiment instead of the laser system. The MDL pro is also transportable which fulfills the need of next-generation AMO systems and supports further compactification and mobilization of state-of-the-art lab-based experiments.

The TA pro is the flagship product of TOPTICAs high power tunable diode laser solutions. Its tapered amplifier technology allows for high power with excellent beam quality, while at the same time maintaining the favorable spectral properties of the pro master laser. The TA pro is a completely revised version of a very well-established laser system, the TA 100. It has been optimized for extreme stability and ease of use, and has proved these properties in numerous tests in TOPTICAs and customers´ laboratories.

The grating stabilized diode laser SHG pro is a medium power solution, for applications such as spectroscopy of atoms, ions and molecules, laser cooling and interferometry. Designed in TOPTICA’s proprietary pro technology, it combines best performance and ease-of-use – at moderate initial and operating costs. The system now includes fully-automated push-button coupling optimization into the SHG cavity and the output fiber. The package comprises a solid laser head and a DLC pro control rack. It can be upgraded to a TA-SHG pro, if an appropriate amplifier source is available.

The TA-SHG pro system, part of the UV / RGB solutions, comprises a tunable diode laser, a high power semiconductor (TA) and an integrated frequency doubling stage (SHG pro). Alternatively, it is available with a fiber (FA) or Raman fiber (RFA) amplifier. The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability. The system now includes fully-automated push-button coupling optimization into the TA chip, the SHG cavity and the output fiber, as well as output power stabilization. It provides tunable laser radiation for spectroscopy, laser cooling, optical data storage, holography and interferometry.
