ps fiber amplifier and gratings compressor
摘要
对掺镱双包层脉冲光纤放大器进行实验研究.当用入纤功率为1.9 W的半导体激光器激光泵浦0.5 m长的双包层掺镱光纤时,把平均功率为7 mW、重复频率25.4 MHz的激光放大到505 mW,相应的单脉冲能量为19.8 nJ,经过光栅对压缩后,得到2.7 ps的脉冲激光.
Abstract
Experiment of the double-clad Yb-doped fiber amplifiers is discussed. The signal with 7 mW average power at 25.4 MHz repetition rate is amplified to 505 mW by using 0.5 m length of double-clad Yb-doped fiber when launched pumping power is 1.9 W, corresponding to a pulse energy of 19.8 nJ. The width of the pulses is compressed to about 2.7 ps by grating pair compressor.
