通过结合二次谐波产生和混合Ti:稀土-Nd:玻璃太瓦激光链的波前校正,我们能够产生高于10(19)W/cm(2)的聚焦强度,估计强度对比度为10(9):1。激光器的频率通过使用I型KDP晶体加倍,并且波前校正通过耦合到波前传感器的可变形反射镜来实现。
By combining second-harmonic generation and wave-front correction of a hybrid Ti:sapphire-Nd:glass terawatt laser chain, we were able to generate a focused intensity above 10(19) W/cm(2), with an estimated 10(9):1 intensity contrast ratio. The frequency of the laser is doubled by use of a type I KDP crystal, and wave-front correction is achieved with a deformable mirror coupled to a wave-front sensor.
