Efficient carrier-envelope phase tunable mid-infrared frequency combs based on CW-seeded optical parametric generation

We present an efficient method for generating frequency combs in the mid-infrared (MIR) spectral range in bulk lithium niobate crystals as well as in waveguides. Our approach is simple and robust, since it is based on single-pass configuration of femtosecond Optical Parametric Generation (OPG) seede...
