摘要
报道了一种大啁啾脉冲输出的全光纤展宽脉冲锁模激光器,以非线性偏振旋转(NPR)实现自启动锁模。激光器其余部分为全单模光纤(SMF)结构,提供很大的正色散,光栅对提供色散补偿,输出展宽脉冲。实验中得到了重复频率36.96 MHz,单脉冲能量1.81 nJ的稳定锁模脉冲序列,使用频谱分析仪观测得到脉冲序列一次谐波信噪比(SNR)达到80 dB。直接输出脉冲有很大的正啁啾,脉宽为2.17 ps,经过腔外压缩可获得70 fs的脉冲。这种能压缩到百飞秒量级的大啁啾脉冲非常适用于光纤啁啾脉冲放大(CPA)系统。
Abstract
A stretched-pulse mode-locked fiber laser which can generate giant-chirp is reported. The nonlinear polarization (NPR) is applied to start the mode-locking. The laser consists of long single mode fiber (SMF) providing large normal dispersion, and grating pairs are utilized for compensation. The mode-locking laser operates at the normal-dispersion region, generates giant-chirp pulses of 2.17 ps and pulse energy of 1.81 nJ at a repetition rate of 36.96 MHz. The giant-chirp pulses are dechirped to a pulse duration of 70 fs. A more than 80 dB signal-to-noise ratio (SNR) for fundamental harmonic of the pulse train is observed in radio frequency analyzer. This kind of giant-linear chirp mode-locking laser is very suitable for chirp pulse amplification (CPA) system.
