A practical way to generate UV light is by converting more easily obtained infrared or visible laser beams into the UV light using nonlinear optics--harmonic generation processes in crystals. This works well for producing light in nearly all of the UV A range (315 nm – 400 nm), the longest of the UV wavelengths. There are several crystals that can do this job...
Read MoreOptical fabrication operations such as grinding and polishing leave traces in the material below the surface being worked and while subsurface damage seems inevitable GAMDAN Optics has proven to minimize SSD. See the photos we took in our lab and the results.
Read MoreOPOs can use a wide range of laser pump beams. The pump lasers can be continuous or pulsed. Pulsed pump lasers might have almost any pulse length, ranging from Q-switched lasers to mode-locked lasers. The OPO will generally produce output with a temporal profile similar to the pump laser. CW pumps drive CW OPOs; pulsed pumps drive pulsed OPOs.
