Abstract
An influence of multi-line CO laser focusing on spectral characteristics of broadband sum-frequency generation in ZnGeP2 nonlinear crystal was experimentally and numerically studied. Maximal frequency conversion was experimentally observed under tight focusing of the multi-line rather than single-line CO laser. The tight focusing resulted in broadening sum-frequency generation spectrum and increasing total, i.e. integrated over the spectrum, frequency conversion efficiency. These effects were due to increasing phase-matching bandwidth and angular dispersion. Maximal conversion efficiency of the multi-line CO laser was numerically demonstrated to take place at the focal length of 0.4 times that for the single-line one.
