technical field

The invention relates to the technical field of solid-state lasers, in particular to a laser that can make the emitted light of the solid-state laser meet the expected effect.

Background technique

A solid-state laser is a type of laser that uses solid-state laser material as a working substance. Its working medium is a small amount of activated ions uniformly doped into the crystal or glass as the matrix material. For example: a laser doped with trivalent neodymium ions in yttrium aluminum garnet crystals can emit near-infrared lasers with a wavelength of 1050 nanometers.
