摘要: We report on a 1.57-µm wavelength singly resonant optical parametric oscillator (OPO) using noncritically phase-matched KTP crystal intracavity pumped by an electro-optically Q-switched Nd:YAG laser. A simple model for numerical calculation of the temporal profile laser and signal pulses developed inside OPO (IPOPO) resonator is described. Working conditions single-pulse multipulse parametric oscillation are established. single pulse of 8.1-mJ output energy was obtained when three times above pulsed IPOPO threshold. duration 5.9 ns was measured at 1.5 times above threshold IPOPO.
