摘要: In this paper, the influence of temperature on the intracavity optical parametric oscillator (IOPO) is investigated by using the stimulated temperature-dependent emission cross section of laser crystal. The rate equations under plane wave approximation have been used for simulation of signal output pulse. Results show that the signal output pulse width is decreased by increasing the laser crystal temperature. Also, the signal output energy is increased by the increasing of the laser crystal temperature. The simulation results for IOPO based on Nd:YAG and Nd:YVO4, show that the signal pulse energies are increased by 3.2 and 5.6 times respectively when the laser crystal temperature increased from 15℃ to 300℃. The presented model indicates that the temperature sensitivity of Nd:YVO4-based IOPOs is more than that of Nd:YAG-based IOPOs which is expected from a physical point of view.

关键词: nonlinear optic, two-wave mixing, parametric oscillators and amplifiers
