【摘要】 本文讨论了对于人眼安全KTP光学参量振荡器存在一个最佳泵浦脉宽 ,此时OPO阈值的变化最小 ,尤其是对于剩余泵浦光被完全反射回去的单谐振OPO。当泵浦脉宽与最佳泵浦脉宽相近时 ,所需泵浦脉冲能量最小。这对设计小型低阈值OPO器件有极大的指导意义。更多还原

【Abstract】 It is shown that for pulsed eye-safe KTP optical parametric oscillators.there is an optimum pump pulse width at which the OPO threshold fluence is a minimum especial for single resonator OPO with pump reflection.The pulse energy requirement for the pump laser may be substantially lower at a pulse width close to the optimum.It is extreme help for lower threshold mini-KTP OPO design.更多还原
