CdSiP2 (CSP) is a nonlinear optical chalcopyrite semiconductor developed as a wider-band-gap analog of ZnGeP2 (ZGP) to enable mid-infrared generation. Two laser architectures were explored to pump CSP crystals at 2 microns. The first was a ring OPO w

CdSiP2 (CSP) is a nonlinear optical chalcopyrite semiconductor developed as a wider-band-gap analog of ZnGeP2 (ZGP) to enable mid-infrared generation with widely-available 1- and 1.55-micron pump laser sources. CSP has an even higher nonlinear coeffi

We report on a widely tunable, nanosecond-pulsed CdSiP2 OPO pumped by a 1.57-micron source. The OPO was angle tuned across the 2–5 micron spectrum producing over 2 mJ at 32% conversion efficiency.
