Toptica Frequency Converted Laser Diodes

TA SHG pro 03

Impressive though the success story of semiconductor lasers has been, there are still several spectral "gaps", wavelengths that cannot be directly accessed with laser diodes. However, nonlinear frequency conversion techniques can be employed to generate tunable laser radiation in the UV, blue and green spectral range. TOPTICA offers state-of-the-art laser systems based on second harmonic generation (SHG), sum frequency generation (SFG) and fourth harmonic generation (FHG).

Toptica DL DFB: Tunable Distributed Feed-back Lasers

DFB pro 03

Distributed feedback (DFB) lasers offer wide frequency tuning and high output power in a compact, rugged setup. The frequency selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures single-frequency operation without any bulk optics. A wide variety of DFB diodes is available from stock; custom wavelengths can be provided even in low quantities.

Toptica Product Focus: Continuously Tunable Lasers

TOPTICA Tuesday 20170530 400x650 CTL

Wide mode-hop-free tuning is important for many exciting applications: for example resonant excitation of small structures like quantum dots and micro-cavities as well as molecular spectroscopy or components testing. TOPTICA is specialized in tunable diode lasers with excellent precision, reliability and ease-of-use.

For example, TOPTICA’s CTL – continuously tunable laser – enables mode-hop-free tuning of up to 110 nm at several central wavelengths. Wide scans can be performed with highest resolution and narrow linewidth, and CTL features high absolute and relative wavelength accuracy as well as high power.

In combination with its fully digital controller DLC pro, the CTL laser is easy to use and operate via touch-screen and knobs as well as via remote PC GUI and command language. The low noise and drift levels of the controller make the CTL series even more stable and lowest-noise.

Toptica DL Pro: Tunable diode laser with digital control DLC pro


Toptica's 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 DL pro HP diode laser features a special resonator design, which allows for higher single-mode output powers from "visible" laser diodes. Like the DL pro, it is an extended cavity diode laser (ECDL). Both lasers feature various modulation inputs and may be equipped with various options like fiber coupling, beam shaping etc. The lasers may also be driven by the economic Sys DC 110 laser control, however we highly recommend the DLC pro due the superior performance, especially for the DL pro HP lasers.
