Optical Heterodyne Detection for Spectral Characterization of Few Longitudinal Mode Fiber Lasers

Not Accessible

Your library or personal account may give you access

Abstract

Fiber lasers have come to a great prominence when it comes to stable high power and excellent beam quality. They are used in industry for material processing, space applications as well as in medicine for precise surgery. Despite their widespread application they are not understood completely when it comes to longitudinal mode (LM) with stochastic phase relations and resulting nonlinear effects like Self-Phase-Modulation (SPM), Stimulated Raman Scattering (SRS) and Stimulated Brillion Scattering SBS. In 2015 S. Sugavanam and D. V. Churkin published a report on spectral characterization of random fiber lasers [1], which shows high spectral resolution with 90 Hz scan rate.
