受激布里渊散射自调Q产生高功率白光超连续谱
Stimulated Brillouin scattering self Q-switching generates high-power white light supercontinuum spectrum
摘要
Abstract
To generate a broader spectrum,higher power,and a more streamlined white light supercontin-uum output,this research investigates the application of self Q-switching technology in producing high-power white light supercontinuum through stimulated Brillouin scattering(SBS)and Rayleigh scattering(RS)mechanisms in optical fibers.The experimental setup employed a semi-open cavity structure com-prising ytterbium-doped fiber,photonic crystal fiber,and high-reflectivity grating.Without external pulse modulation,the study successfully achieved a high-power white light supercontinuum spectrum spanning 410-1 700 nm,with an output power of 24 W and a repetition frequency of 188.7 kHz at a pump power of 97.4 W.The light-to-light conversion efficiency reached 24.6%.These findings demonstrate that the white light supercontinuum fiber laser based on the SBS self Q-switching mechanism represents a novel light source with significant advantages,including a simplified structure,extensive spectral range,and su-perior spectral uniformity.The research provides an innovative design approach for developing high-power white light supercontinuum spectral light sources.关键词
