Er:YAG Laser Crystal
Er:YAG Laser Crystal
Er:YAG lases at 2940 nm. This band lies at the hydroxyl absorption peak, where it is strongly absorbed. The crystal offers high slope efficiency, operates well at room temperature, and works in a relatively eye-safe wavelength range.
Key Features
- High slope efficiency
- Operates well at room temperature
- Relatively eye-safe wavelength range
- Lases at 2940 nm, at the hydroxyl absorption peak
