SHG

SHG (Second Harmonic Generation) is historically the main application for non-linear crystal materials. During this process, two photons at fundamental wavelength are converted into one photon at half the fundamental wavelength (i.e. twice the frequency).

Today, the most SHG crystals are cut for the conversion of 1.064µm solid-state lasers into green (532nm) but we also manufacture SHG crystals for other visible wavelenghts (red, blue, yellow) or in the UV. The SHG crystals we manufacture for green (527nm, 532nm) are checked on our SHG test bench.
