Numerical Simulation of Highly-Efficient Fiber Laser Cavity Protective Coating for Environmental Noise Desensitization

Abstract

The influence of environmental acoustic vibrations on cavities of fiber lasers may significantly decrease their parameters. It is shown that protective coatings for desensitization of fiber laser cavities with efficiency up to -95 dB compared to the level of acoustic sensitivity of optical fiber with standard acrylate coating can be produced by application of composite multi-layer structures of different-type materials.
