摘要
设计了一种新型高功率光纤隔离器,其以球面透镜和铽镓石榴石(TGG)晶体作为器件核心,能较好地满足高功率光纤激光器的要求。测试结果显示,在1 064±15 nm的范围内,隔离器所能承受的最高功率为45 W,插入损耗(IL)小于0.61 dB,隔离度(ISO)大于24.5 dB。
Based on the spherical lens and terbium gallium garnet（TGG）,a novel optical fiber isolator with high-power is designed,which can fully meet the requirements of the high-power fiber laser.Within the wavelength range of 1 064±15 nm,the measured results show that the insertion loss is below 0.61 dB,the isolation is larger than 24.5 dB and the laser can work stably when the input power is 45 W
