Experimental Study on MOPA System of Four-Pass Configuration with Optical Fiber Phase-Conjugator
摘要
报道了应用φ100 mm和φ200mm两种芯径光纤作为相位共轭镜时,四通放大主振荡功率放大器(MOPA)系统的SBS能量反射率、稳定性、保真度、输出能量等性能参量的变化趋势.应用φ100mm光纤时四通放大系统最大输出能量为6mJ,可以获得的最大反射率为41%,SBS能量阈值约为0.73 mJ;应用φ200mm光纤时可以获得最大激光输出能量为21mJ,可以获得的最大反射率为37%,SBS能量阈值约为1.1mJ.
Abstract
Using optical nber with diameter of 0100 mm and ¢200 mm as phase-coryugator, the energy reflectivity, stability, fidelity and output energy in ΜΟΡΑ system of four-pass configuration are presented Applying optical fiber of 0100 mm core diameter, 6 mJ output energy and 41% SBS reflectivity have been obtained, SBS threshold is 0.73 mJ. Applying optical fiber of 0200 nun core diameter, 21 mJ output energy and 37% SBS reflectivity have been obtained, SBS threshold is 1.1 mJ.
