We have demonstrated a high-energy, eye-safe, KTP-based intracavity optical parametric oscillator (IOPO) pumped by a QCW diode-pumped electric-optical Q-switched Nd:YAG. A signal pulse of 31.5mJ energy at 1572nm wavelength was demonstrated at 10Hz with 3.48ns pulse duration. The peak power of the pulses amounted to 9.1MW. The average conversion efficiency from Q-switched 1.064μm wavelength input power to OPO signal output power was up to 10.5%.
