Phase-stabilized, 15 W frequency comb at 28–48 μm
Phase-stabilized, 15 W frequency comb at 28–48 μm
We present a high-power optical-parametric-oscillator (OPO) based frequency comb in the mid-IR wavelength region. The system employs periodically poled lithium niobate and is singly resonant for the signal. It is synchronously pumped by a 10 W femtosecond Yb:fiber laser centered at 1.07 microm. The idler (signal) wavelength can be continuously …
