摘要

Partially deuterated KDP is an ideal nonlinear crystal for second-harmonic generation (SHG) of femtosecond lasers at 1μm, which features with vanished group-velocity mismatch at its retracing point of phase-matching. We numerically investigate the characteristics of SHG with femtosecond lasers in a partially deuterated KDP, which shows that group-velocity dispersion plays an important role. This spectrally non-critical phase-matching configuration can support both high efficiency and large acceptance bandwidth.
