Abstract

Backwards Wave Optical Parametric Oscillators (BWOPOs) eliminate the need for a resonant cavity, offering a compact and robust alternative to traditional OPOs. In this study, a BWOPO using a PPKTP crystal with a 765 nm poling period was pumped by a Q-switched laser at 1030 nm, delivering 40 μJ pulses. The backward wave generated at 2.8 μm exhibited a narrow spectral bandwidth of 1.75 GHz, despite the pump's broad 360 GHz bandwidth. The extracted pulse energy was around 5 μJ. These results highlight the BWOPO's potential for applications requiring precise wavelength control and stability.
