We present the design and construction of an all-fiber high-power optical parametric chirped-pulse amplifier working at 1700 nm, an important wavelength for bio-photonics and medical treatments. The laser delivers 1.42 W of output average power at 1700 nm, which corresponds to ∼40 nJ pulse energy. The pulse can be de-chirped with a conventional grating pair compressor to ∼450 fs. Furthermore, the laser has a stable performance with relative intensity noise typically below the -130 dBc/Hz level for the idler pulses at 1700 nm from 10kHz to 16.95 MHz, half of the laser repetition rate f/2.

我们展示了工作在 1700 nm 的全光纤高功率光学参量啁啾脉冲放大器的设计和构造，这是生物光子学和医疗的重要波长。该激光器在 1700 nm 处输出平均功率为 1.42 W，相当于 ∼40 nJ 脉冲能量。可以使用传统的光栅对压缩器将脉冲去啁啾至~450 fs。此外，该激光器具有稳定的性能，对于 1700 nm、10kHz 至 16.95 MHz 的空闲脉冲，相对强度噪声通常低于 -130 dBc/Hz 水平，是激光重复率 f/2 的一半。
