在大芯径氟碲酸盐-硫系光纤级联系统中产生高功率中长波超连续谱激光
Generation of High-power Mid and Long Wave Supercontinuum Laser in A Large-mode-area Fluorotellurite-chalcogenide Fiber Cascade System
摘要
Abstract
This work reports a high-power flat mid-infrared supercontinuum laser system based on a large-mode-ar-ea low-loss fluorotellurite fiber cascades with a large-mode-area chalcogenide fiber.To effectively extend the spectral coverage of mid-infrared supercontinuum and improve its flatness,a novel high peak power Raman-soliton femtosec-ond laser source is used as the pump.Through cascading with the large-mode-area As₂S₃ fiber,the output power of the supercontinuum can reach 2 W at the maximum input power,with the spectral edge extending to 5.3 µm and the 10 dB spectral bandwidth covering the range of 2-4.6 µm.The proposed supercontinuum generation system,which utilizes fluorotellurite fiber as the transition fiber cascades with chalcogenide fiber,achieved higher supercontinuum output power in the mid and long wave infrared region compared to other previously reported schemes.This work pro-vides a superior approach for realizing highly stable mid and long wave supercontinuum laser sources in the future.关键词
