Background:

Optical parametric oscillators (OPOs) are crucial for generating tunable laser light.
Periodically poled KTiOPO4 (PPKTP) is a nonlinear crystal with potential for OPO applications.
Challenges in OPO development include low threshold power and material limitations like absorption.

Purpose of the Study:

To investigate the performance characteristics of a doubly resonant PPKTP OPO, including threshold power and tunability.
To assess the material's suitability for high-power operation by examining nonlinear absorption phenomena.

Main Methods:

Fabrication of a 10-mm-long flux-grown PPKTP crystal with a 9-µm quasi-phase-matching period.

Utilizing a miniature frequency-doubled Nd:YAG laser as the pump source.

Operating the doubly resonant OPO near room temperature and tuning output via crystal temperature and cavity length.

Main Results:

Achieved a low threshold power of 51 mW for the doubly resonant OPO.
Demonstrated wavelength tuning of signal and idler from 1037-1093 nm by adjusting crystal temperature (32-38°C) and cavity length.
Observed no green-induced infrared absorption up to high pumping intensities (~4.5 kW/cm²), unlike other nonlinear crystals.

Conclusions:

The successful demonstration of a CW PPKTP OPO establishes a new, efficient nonlinear optical source.
The low threshold power and broad tuning range make this device suitable for various spectroscopic applications.
The absence of green-induced infrared absorption highlights PPKTP's robustness for high-intensity nonlinear optical processes.
