Green Lasers Overview
532 nm lasers are by far the most common green laser available on the market today. They are produced by frequency doubling Nd: YAG, Nd: YVO, or Nd: Glass solid-state lasers to provide 532 nm laser light. Solid-state 532 nm lasers are available with both pulsed and Raman spectroscopy, because of their narrow spectral linewidth, where flashlamp-pumped pulsed 532 nm lasers are beneficial in applications requiring high peak power such as laser ablation and tattoo removal. Recent advancements in GaN technology has allowed for the development of green laser diodes, which have filled in the lower wavelength range with diodes available between 505 nm and 520 nm. Green laser diodes are available in both single-mode and multi-mode beam profiles, and with either free space or fiber coupled outputs. OEM packages and laser modules are available for both green DPSS and diode lasers.
