Efficient Second-Harmonic Generation of Broadband Radiation in the Nonlinear Crystal with Constant Axial Temperature Gradient

Abstract

Efficiency of second-harmonic generation (SHG) of broadband light pulses is limited by chromatic dispersion of a nonlinear crystal. The group velocity mismatch between first and second harmonic pulses results in diminishing overlap between pulses as they propagate in a nonlinear crystal. Particularly, when fundamental pulses are chirped (phase-modulated), the group velocity mismatch causes loss of phase-matching even before complete walk-off of pulse envelopes occurs [1]. This limits the optimal crystal length and, as a result, overall conversion efficiency. In order to maintain the high conversion efficiency in a shorter crystal, pulse irradiance has to be increased. However, the pulse irradiance is limited by the crystal damage threshold. Thus, achieving the high conversion efficiency of broadband pulses is not a trivial task, especially when the pulses are not bandwidth-limited.
