AVIA LX 355-20 Laser | Coherent

…lifetime of first generation DPSS lasers with UV or green output was often limited by optical damage to the harmonic crystals that are used to frequency double or triple the laser’s fundamental near-infrared output beam. Coherent has manufactured more ultraviolet industrial lasers than anyone else.…

…field illumination. Direct write. This requires a controlled TEM00 beam and as deep UV as possible. This can be either a frequency doubled Argon Laser (FreD) or a frequency doubled solid-state green laser such as Azure. Unfortunately, it is difficult to test these optical components with a pulsed…

…effect occurs when a sample is irradiated with UV, visible or IR light and a small fraction of the incident radiation is scattered and shifted at frequencies that correspond to vibrational transitions specific of the sample. The Raman signal is much weaker than the incident and scattered light, so…
