Description

Specification

Cr:YAG Description

Cr:YAG stands for Chromium-Doped Yttrium Aluminum Garnet. It is a type of laser crystal that is doped with chromium (Cr) ions. Cr:YAG crystals are used as a gain medium in solid-state lasers. Cr:YAG crystals are known for their ability to produce laser light in the near-infrared (NIR) region of the electromagnetic spectrum. The specific properties of Cr:YAG crystals, such as their emission wavelengths and efficiency, can be tailored by adjusting the chromium dopant concentration and the design of the laser system. This allows for flexibility in meeting the requirements of different laser applications.
