Single-Longitudinal-Mode Laser at 1123 nm Based on a Twisted-Mode Cavity

Single-Longitudinal-Mode Laser at 1123 nm Based on a Twisted-Mode Cavity

A single-longitudinal-mode (SLM) Neodymiun-doped Yttrium Aluminium Garnet (Nd:YAG) laser at 1123 nm was first demonstrated with a twisted-mode (TM) cavity. By eliminating the spatial hole burning phenomenon, a stable SLM 1123 nm laser output was obtained. An efficient TM cavity was designed based on...

An efficient TM cavity was designed based on the Brewster plate with high reflection under <i>s</i>-polarization radiation. At an incident pump power of 7.65 W, the maximum output power of 689 mW was obtained. The corresponding optical conversion efficiency was about 9%. The center wavelength was 1122.58 nm and the line-width was <140 MHz.https://www.mdpi.com/2073-4352/11/1/581123 nm radiationsingle longitudinal modetwisted mode cavityhigh efficiency
