What Is the Wavelength of a Green Laser?
Visible green light spans about 495 to 570 nm. The most common green laser wavelength is 532 nm. It is made by frequency-doubling (second harmonic generation) the 1064 nm infrared output of a diode-pumped Nd:YAG or Nd:YVO4 crystal. This is the wavelength used in most green laser pointers, alignment lasers and Raman spectrometers.
Other green wavelengths come from other laser lines:
The human eye is most sensitive near 555 nm, so a 532 nm green beam looks several times brighter than a red beam of the same power. CrystaLaser green lasers are available at all of the wavelengths above, with CW power up to 400 mW at 532 nm and single-frequency versions with coherence length over 100 m. See the specifications below, the full laser wavelength table, or the Raman laser selection guide.
