Single frequency solid state laser

Overview

Bramms technology is a laser technology that selects a single longitudinal mode in the laser resonant cavity through the Michelson interferometer and volume Bragg full system grating. Through this technology, the single frequency continuous laser output can be feedback locked, and the single frequency laser output with high stability, very narrow linewidth and excellent beam quality can be provided. The parameters of single frequency laser can be comparable to gas lasers such as argon ion laser, and the conversion efficiency is much higher than that of gas laser, and the volume is much smaller than that of gas laser. It is an ideal laser to replace He-Cd laser and argon ion laser. It can be used for holography, interferometer, semiconductor wafer detection, nonlinear optics, pump source, etc.
