摘要：
Light pulses of 149 μm wavelength and 700 ps duration are generated by non-collinear phase-matched difference frequency mixing of laser pulses at 1053.5 and 1061 nm in a (110) cut GaP crystal. The pump laser pulses are generated in a time-synchronized mode-locked double-frequency Nd:glass laser system consisting of a silicate glass branch and a phosphate glass branch. A photon conversion efficiency of 4 × 10−6 is achieved. The non-linear susceptibility constant of GaP is determined to be d14 = (10 ± 1) pm V−1.
