摘要
我们报导清洗技术提高强烈超短波的激光脉搏的对比比率的新脉搏。脉搏时间的清洁工基于由使用 BK7 玻璃板的非线性的椭圆旋转被开发，并且为毫焦耳水平飞米秒的二个数量级的对比比率改进输入脉搏被表明，脉搏清洁工的全部的传播效率是 16.7% 。
We report a new pulse cleaning technique to enhance the contrast ratio of intense ultra-short laser pulses. A pulse temporal cleaner based on nonlinear ellipse rotation by using BK7 glass plate is developed, and a contrast ratio improvement of two orders of magnitude for the milli-joule level femtoseeond input pulses is demonstrated, the total transmission effieiency of the pulse cleaner is 16. 7%.
