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

Crystals, 2021
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.
