Nd:KGW

Nd:KGW晶体是一种可以实现高浓度掺杂的激光晶体,因为该晶体可以与高浓度的Nd离子混合并且具有较大的发射面积,因此其单脉冲和低重复激光性能优于Nd:YAG 。Nd:KGW晶体的吸收带在808 nm处,可以有效地与LD泵浦光源耦合(发射波长为808 nm),从而提高其发光效率。此外,它的半高和半宽为12 nm,使其能够适应LD发射波长随温度的漂移,这有利于进行二极管泵浦KGw激光实验和器件研究。Nd:KGW不仅可以实现自由振荡,Q开关,锁模操作,还可以实现拉曼转换。

Nd:KGW晶体是由受激拉曼散射产生的晶体,经过倍频后可以成为可见光波段的多波长光源。

Nd:KGW晶体的拉曼特性取决于其高激发光束截面、低泵浦阈值、高输出能量、高转换效率以及两个高拉曼增益系数(768和901 cm-1)。拉曼晶体的基频光分别为911 nm,1067 nm和1351 nm,经过倍频后可产生0.455 um,0.533 um和65 um的红,黄和蓝光,可用于材料加工,光通信,遥感,医药,环境监测,精密计量等领域。
