Broadly tunable MgO: PPLN mid-infrared OPO synchronously pumped by Innoslab amplifier

In this paper, we demonstrated a broadly tunable MgO:PPLN mid-infrared optical parametric oscillator(OPO) synchronously pumped by a picosecond(ps) Innoslab amplifier. The signal wavelength tuning range from 1415 nm to 1557 nm and idler from 3362 nm to 4290 nm were achieved by changing the temperature and translating the grating of the MgO:PPLN, within which the highest optical-optical conversion efficiency from pump power to OPO output was 17.5%.Under the synchronously pumping power of 16 W with 116.9 MHz pulse repetition rate, 1.33 W of signal light at 1518 nm and 1.26 W of idler light at 3558 nm were obtained simultaneously.
