摘要

我们通过光学频率梳锁相Nd:YAG非平面环形振荡器(NPRO)来缩小1083 nm激光器的线宽。梳子将碘稳定NPRO (<2 kHz)的窄线宽从1064 nm转移到整个可见光和红外区域的数千个波长。锁相到梳的激光将具有NPRO的窄线宽。我们在1083 nm的外腔二极管激光器上演示了这种线宽缩小方案，显示线宽从54 kHz减少到5.5 kHz，减少了10倍

Narrowing laser linewidth using a stabilized optical frequency comb

We narrow the line width of a 1083 nm laser by phase-locking to an Nd:YAG non-planar ring oscillator (NPRO) via an optical frequency comb. The comb transfers the narrow linewidth of the iodine-stabilized NPRO (<2 kHz) from 1064 nm to thousands of wavelengths throughout the visible and infrared regimes. Lasers phase-locked to the comb will have the narrow linewidth of the NPRO. We demonstrate this linewidth-narrowing scheme for an external-cavity diode laser at 1083 nm, showing a 10-fold reduction in linewidth from 54 kHz to 5.5 kHz
