Abstract

We have demonstrated a 243mJ, eye-safe, injection seeded, non-critically phase-matched (NCPM), singly resonant oscillator (SRO), KTA ring-cavity optical parametric oscillator (OPO). The OPO was pumped with a single mode 7ns FWHM, 30Hz, Q-switched, Nd:YAG at a wavelength of 1064.162nm. The OPO was injection-seeded utilizing a single longitudinal (SLM) distributed feedback (DFB) diode laser. As a result, the KTA OPO generated an eye-safe signal wavelength of 1535.200nm with a maximum energy of 243mJ, a conversion efficiency of 27%, a cavity mode seed range of 853MHz FWHM, and a maximum M2=30. This high energy, eye-safe OPO could potentially increase the sensitivity and range capabilities of elastic LIDAR and DIAL systems which are used for remote sensing applications.
