摘要

我们演示了基于二极管激光产生的锁模脉冲，其时间宽度为290fs，中心波长为1067nm，峰值功率为69w。激光二极管以1.05 GHz的重复频率在外腔结构中工作。激光操作被动模型锁定与反向偏压吸收部分。通过优化的光栅压缩器，将啁啾输出脉冲压缩到接近变换极限的位置。这种定制的脉冲压缩提供几乎变换有限的脉冲，其规格足以用于太赫兹时域光谱或非线性显微镜应用。

Diode Laser-Based Generation of Mode-Locked Pulses at 1067 Nm (290 fs, 69 W Peak Power)

We demonstrate the diode laser-based generation of mode-locked pulses with 290 fs temporal width and 69 W peak power at a centre wavelength of 1067 nm. The laser diode is operated in an external cavity configuration at a repetition rate of 1.05 GHz. The laser operates passively modelocked with a reverse biased absorber section. The chirped output pulses are compressed close to the transform limit by means of an optimized grating compressor. This tailored pulse compression delivers almost transform limited pulses with specifications sufficient for THz time domain spectroscopy or nonlinear microscopy applications.
