【摘要】 报道了光折变LiNbO₃:Fe晶体中双光束耦合和四波混频的脉动现象。认为这种脉动现象起因于LiNbO₃:Fe晶体中的陷阱重复荷电波在光折变材料中感应出的运动折射率光栅。更多还原

【Abstract】 The optical pulsation phenomenon which occurs in two-beam coupling and four-wave mixing in photorefractive LiNbO₃:Fe crystal is reported. This phenomenon is considered to originate from the trap-recharging wave in LiNbO₃:Fe crystal, which induces a moving phase grating in the photorefractive material.更多还原
