| Abstract: | 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 |
