Article Synopsis

The study discusses the development of a singly resonant optical parametric oscillator leveraging a 5% MgO:PPLN partial cylinder and a sub-nanosecond microchip laser that operates at 1064 nm frequency with a 1 kHz repetition rate.
The oscillator is capable of continuous wavelength tuning ranging from 1410 nm to 4330 nm through the rotation of the cylinder.
The system produces several microjoules of energy and maintains a beam quality factor M of less than 3, indicating effective beam performance.

A pulsed, single longitudinal mode, wavelength-tunable Tm:YAP laser is reported. We demonstrate 1 kHz stable operation with 230 µJ, 50 ns pulses and a spectrum linewidth narrowed below 4 pm (FWHM) close to the Fourier transform limit by use of a volume Bragg grating and a YAG etalon. The output wavelength was tuned from 1940 to 1960 nm owing to a transverse chirp of the period of the Bragg grating.
