Stabilization of the generation spectrum of a pulsed solid-state Nd–YAG laser with a multiloop cavity

Abstract

We propose a method of stabilizing the frequency and narrowing the generation bandwidth of a pulsed solid-state Nd–YAG laser with dynamic self-adaptive multiloop cavity, which is based on the introduction of a stationary intracavity-volume Bragg grating. This allows the laser frequency to be stabilized and the spectral line width to be reduced from 18 to 4 pm.
