473 nm Blue DPSS Lasers

473 nm is produced by frequency-doubling 946 nm Nd:YAG emission. It delivers clean TEM₀₀ spatial beam quality and narrow linewidth, making it an established excitation source for optogenetics (ChR2 photostimulation), confocal fluorescence microscopy (CFP, GFP), flow cytometry, and holography. Compare compact CW DPSS modules, low-noise variants, and high-stability systems below.
