摘要
利用Nd:YAG再生放大器,对1064 nm掺镱锁模全光纤激光器输出的皮秒脉冲进行了功率放大.研究分析了掺镱锁模全光纤激光器输出脉冲对Nd:YAG再生放大器能量提取效率的影响,通过对掺镱锁模全光纤激光器自相位调制的控制,减少了输出光谱的振荡结构,提高了掺镱锁模全光纤激光器对Nd:YAG再生放大器的能量提取效率,实现了对锁模全光纤激光器输出的中心波长1064.4 nm,3 dB光谱宽度0.35 nm、脉宽11 ps、单脉冲能量为3.2 nJ、频率为38 MHz的锁模脉冲的再生放大,得到输出重复频率为1 kHz,最大的单脉冲能量为1.3 mJ的皮秒脉冲.
The picosecond pulse from 1064 nm Yb-doped all-fiber mode-locked laser is amplified by Nd： YAG regenerative amplifier. Research is focused on the influence of Yb-doped all-fiber mode-locked laser on the e？ciency of energy extraction of Nd： YAG regeneration amplifier. In order to increase the e？ciency of energy extraction, spectral oscillatory fringe is decreased by means of restricting the self-phase modulation of Yb-doped all-fiber mode-locked laser. The Nd：YAG regenerative amplifier produces stable pulse energy of 1.3 mJ at a repetition rate of 1 kHz, which is seeded by a Yb-doped all-fiber mode-locked laser, with a low energy of 3.2 nJ, center wavelength of 1064.1 nm, 3 dB bandwidth of 0.35 nm 11 ps duration.
