Single mode Q-switched 1064 nm Nd∶YAG laser with 7 ns pulse width,30 Hz repetition frequency and 1.2 J output energy is adopted to pump single resonance ring cavity KTP optical parametric oscillator (OPO). A 1572 nm eye-safe laser that generated by KTP-OPO is achieved,the maximum output energy is 500 mJ,conversion efficiency is 53%.This laser can be used for laser ranging and target illuminating,etc.
