TOPTICA’s TopMode lasers operate as easily as a HeNe, but also offer higher power and blue wavelengths. The TopMode series sets records in terms of power, coherence and wavelength stability. The proprietary CoHerence-Advanced Regulation Method (CHARM) provides an active stabilization of the lasers’ coherence and ensures continuous single-frequency operation. TopMode and CHARM means nothing less than reliable 24/7 operation.

The XTRA II provides three top features from one single unit: Gaussian beam profile, single-frequency operation and high output power. Incoherent ASE is suppressed by more than 40 dB, turning the XTRA II into the ideal choice for demanding Raman applications depending on a high signal-to-noise ratio. The integration of a high quality optical isolator as a standard feature ensures long term rock solid performance of the XTRA II.

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 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.

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.

Detector for fast, time-resolved (ns) radiant power measurement of pulsed laser diodes and LEDs. Features: Integrating sphere for integration of laser modes and beam profile. Pulse waveform with peak power and pulse energy (in joules) of pulses with pulse lengths in the low ns range. Optional 7 mm measuring aperture for eye safety.
