TOPTICA PHOTONICS AG - High-end laser systems for your scientific or industrial application

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.

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 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 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 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 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 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 FemtoFiber smart family is TOPTICA’s new series of ultrafast fiber lasers available as picosecond or femtosecond versions, based either on Ytterbium-doped or Erbium-doped fiber laser architecture. These systems are dedicated to applications ranging from seed laser purposes, biophotonics to terahertz generation and two-photon polymerization. Optimized for a compact footprint uniting optics and electronics in one box, these robust all-fiber lasers are the perfect choice for flexible OEM integration.

The FemtoFiber pro is the successor of our proven FemtoFiber Scientific (FFS). The FemtoFiber pro includes a different mode-locking mechanism based on saturable absorber mirrors (SAM) and the use of only polarization maintaining (PM) fibers. Both novelties increase the robustness and reliability of the fiber laser even further. The FemtoFiber pro is available with fundamental output at 1560 nm (FemtoFiber pro IR) and also with second harmonic output at 780 nm (FemtoFiber pro NIR).

The FemtoFiber ultra series is TOPTICA's third generation of ultrafast fiber lasers. These lasers provide powerful femtosecond pulses with a ultra-high reliability. The systems use SESAM-mode locked ring fiber oscillators (patented design), followed by a high-power fiber amplifier. For reaching highest reliability levels, only polarization-maintaining fibers are used. All of this is integrated in a unit with a footprint of 25 x 38 cm². The laser systems are easily controlled via Ethernet or USB. A simple graphics user interface (GUI) enables user-friendly access to all laser parameters.
