532 nm Green DPSS Lasers

532 nm is the benchmark visible laser wavelength in modern science and industry. Produced by frequency-doubling 1064 nm Nd:YAG or Nd:YVO₄ crystals, green DPSS lasers are the standard excitation line for Raman spectroscopy, particle image velocimetry (PIV), confocal microscopy (GFP, FITC), flow cytometry, holography, and laser display. Our catalog spans milliwatt single-frequency SLM sources with sub-MHz linewidth to multi-watt Q-switched pulsed systems.
