Widely tunable near-infrared optical parametric oscillator based on a 5%MgO:PPLN partial cylinder pumped at 1064nm by a 1-kHz sub-nanosecond microchip laser

We report the implementation of a singly resonant optical parametric oscillator using a 5%MgO:PPLN partial cylinder pumped by a sub-nanosecond microchip laser emitting 1064nm at a repetition rate of 1 kHz. It is continuously tunable from 1410nm up to 4330nm by rotating the cylinder and a total energy of several microjoules is emitted with a beam quality factor M-2 lower than 3.

Automated summary

We present the implementation of a singly resonant optical parametric oscillator using a sub-nanosecond microchip laser pumped 5%MgO:PPLN partial cylinder. The oscillator emits a continuous tunable output from 1410nm to 4330nm by rotating the cylinder. The emitted energy reaches several microjoules with a beam quality factor M-2 below 3.
