355nm Laser:
Optical activation for an optically triggered power transistor, related Laser is 355nm Passively Q-switch UV solid-state pulsed laser power.
Optically Activated SiC Power Transistors for Pulsed-Power Application
561nm laser:
imaging microscopy: Optical or light microscopy involves passing visible light transmitted through or reflected from the sample through a single lens or multiple lenses to allow a magnified view of the sample. The resulting image can be detected directly by the eye, imaged on a photographic plate, or captured digitally.
