摘要：
In this paper, nonlinear frequency conversion of second harmonic and third harmonic of femtosecond Ti: sapphire laser is theoretically and experimentally studied. Noncolinear type I phase matching process is chosen to generate third harmonic of femtosecond Ti:sapphire laser, and we have obtained conversion efficiency of 6.2% at 260 mu output. The pulse duration is about 169 fs. This work will serve as femtosecond ultraviolet source for time-resolved electron microscopy.
