A compact high peak power eye-safer optical parametric oscillator was constructed by pumping it with a master oscillator power amplifier consisting of a large-mode-area ytterbium doped fiber amplifier and a diode-pumped, passively Q-switched Nd : YAG microchip laser. The master oscillator power amplifier has the maximum output pulse energy of 570 μJ with a 3 nanosecond pulse width and a 3 kHz pulse repetition rate. The compact singly resonating optical parametric oscillator utilized a 50 mm periodically poled Lithium Niobate crystal and generated high peak power 1.5 μm eye-safe laser pulses with more than 140 μJ pulse energy, 3 nanosecond pulse width and 3 kHz repetition rate.

The pulse evolution of mid-infrared optical parametric oscillator based on silicon-on-insulator (SOI) waveguides is numerically investigated. The properties of pulse evolution in the process of optical parametric oscillation have been described. The numerical results show that the threshold of the optical parametric oscillation cavity can be lowered due to the high nonlinearity of the waveguide. The parametric signals initiate to oscillate when the circle trip number is 5 with the appropriate length of the SOI waveguide 7 mm. Meanwhile the peak power of the output signal pulse can be reached to 400 W at the stable situation when the circle trip number is over 10 with the conversion efficiency as high as 5%. This research can supply a kind of way to generate the mid-infrared femtosecond pulse at the highly stable on-chip integration level.
