Yellow and Orange Diode Lasers

Toptica offers lighting solutions based on frequency-doubled grating stabilized diode lasers. According to take infrared and make orange out of it, lasers of the type DL-SHG (Diode Laser Second Harmonic Generator) provide output powers from several mW to a few ten mW depending on the design wavelength in the range of 555 nm to 625 nm. Such lasers can be coarse-tuned by a few nm and allow for some 10 GHz modehop-free fine-tuning. The proprietary design guarantees frequency drifts below 200 MHz/K and coherence lengths of several hundred meters. Main applications of these high-end lasers are spectroscopy and interferometry but also laser cooling or optical pumping of atoms and ions.
