CY0488 Cr:YAG (Chromium-doped Yttrium Aluminium Garnet)

Cr:YAG Description

Cr:YAG denotes Chromium-doped Yttrium Aluminium Garnet. It is a type of laser crystal doped with chromium (Cr) ions. Cr:YAG crystals are used as the amplification medium in solid-state lasers. They produce laser radiation in the near-infrared (NIR) region of the electromagnetic spectrum. Their emission wavelengths and efficiency can be adjusted by modifying the chromium doping concentration and the laser system design. Consequently, the configuration is tailored to meet the requirements of various laser applications.
