论文摘要
中型透明度窗口中的大气分散体呈现出来，尽管在开发超短脉冲激光器时经常被忽略的因素。我们证明，它可以构成数百个fs^2在2-3微米窗口中，并具有典型的激光往返路径长度。使用CR：ZNS超短式激光作为测试床，我们证明了大气分散体对飞秒和chi的脉冲脉冲振荡器的性能的影响，并表明可以通过主动分散控制来补偿湿度的波动，从而极大地改善了几个中级循环循环的稳定性。该方法可以很容易地扩展到MID-IR透明度窗口中的任何超快源。
The atmospheric dispersion in the mid-infrared transparency windows presents and important albeit frequently neglected factor when developing ultra-short pulsed lasers. We show that it can amount to hundreds of fs^2 in 2-3 micron window with typical laser round-trip path lengths. Using the Cr:ZnS ultrashort-pulsed laser as a test-bed, we demonstrate the atmospheric dispersion influence on a femtosecond and chirped-pulse oscillator performance and show that the humidity fluctuations can be compensated by active dispersion control, greatly improving stability of mid-IR few-optical cycle laser sources. The approach can be readily extended to any ultrafast source in the mid-IR transparency windows.
