用提拉法生长的无序石榴石Ca 3（Nb，Ca）5 O 12：Nd 3+在脉冲皮秒激光器中产生5-10-ps的脉冲，其被动锁模序列为120-180 ns，能量为1.6 mJ，波长为1.06 μ m。 脉冲参数的演变沿着列车的调查。 直接的时间分辨测量使我们能够确定激光频率的正线性啁啾，这导致脉冲光谱增宽Δ v = 50-60 cm-1。 啁啾脉冲在外部光栅压缩器中被压缩。 测量的2 ps的脉冲持续时间受到条纹相机的时间分辨率的限制。
Disordered garnets Ca3(Nb, Ca)5O12:Nd3+ grown by the Czochralski method are used in a pulsed picosecond laser to generate 5-10-ps pulses in passive mode-locking trains of 120-180 ns and 1.6 mJ of energy at 1.06-mu-m. The evolution of the pulse parameters along the train is investigated. Direct time-resolved measurements allow us to determine the positive linear chirp of the laser frequency, which causes the pulse spectral broadening of DELTA-v = 50-60 cm-1. The chirped pulses are compressed in the external grating compressor. The measured pulse duration of 2 ps is limited by the time resolution of the streak camera.
