A gain medium is a material that can amplify light or electromagnetic radiation passing through it. This amplification is achieved by exciting the atoms or molecules in the medium, which then emit additional photons that are in phase with the original radiation. This process is known as stimulated emission and is the basis for many laser applications.

Crylink offers a wide range of laser gain medium materials such as Ti:Sapphire, Nd:glass, YLF and more. There are also Passively Q-switched Crystal, nonlinear crystals, bonded crystals, electro-optic crystals, magneto-optic crystals, and more. Optical devices include Pockels Cells, isolator rotators, acousto-optic modulators, and more.

Choosing the right gain medium depends on several factors, including the desired wavelength, power, and mode of operation. It is essential to consider the gain bandwidth, saturation power, and other performance characteristics of the medium to ensure that it meets your specific needs.
