We experimentally explored the design parameter space for periodically poled R b : K T i O P O 4 (PPRKTP) structures in type-II optical parametric oscillators (OPOs) pumped at 1.064 µm and operating in the 1.8–2.5 µm range. This study identifies

We demonstrate 1st order QPM backward SHG in a bulk PPRKTP with a poling period of 317 nm. Using a narrowband nanosecond-source, the crystal demonstrated a conversion efficiency of 17.6%.

We demonstrate 3rd order QPM backward SHG in a bulk PPRKTP with a poling period of 317nm. This is the shortest QPM period ever fabricated. These results pave the way towards 1st order BSHG.

Precision-tunable mJ, nanosecond pulses at 1981.1 nm and 2145.6 nm are generated at 5kHz repetition with an efficiency of 70% in a cavity-free arrangement using a PPRKTP BWOPO pumped by a narrowband DPSSL at 1030nm.

There is an ongoing development of THz sources for high-field applications, especially with the view of potential for THz-driven particle accelerators. For such sources nonlinear materials with high optical damage threshold and low loss are required.
