Toptica Frequency Converted Laser Diodes
- SHG, FHG, SFG
- Deep UV, blue, green, yellow ...
- All solid state laser systems
- CW, single-frequency output
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).
