ultrashort laser pulse meaning in Chinese
超短激光脉冲
Examples
- Ultrashort laser pulse
超短激光脉冲 - In a laser - powered plasma accelerator , an ultrashort laser pulse is focused into a helium jet that is a couple of millimeters long
在雷射电浆加速器里，一个超短的雷射脉冲聚焦到一束大约两、三公?长的氦喷射气流中。 - In the case of ultrashort laser pulse , the effect of finite pulse length is anlyzed , and self - steepening in the front of the pulse will occur when only relativistic nonlinearity is considered
同时，对于超短脉冲传输，分析了有限脉冲宽度效应对傍轴方程的修正，当只考虑相对论性非线性效应时将会引起激光脉冲前沿自陡峭。 - The laser beam spot evolution and electron density in the guiding range are evaluated with the burn pattern and the measured conductivity . the above results will be useful in ultrashort laser pulse amplification and future research in ultrashort intense laser propagation in plasmas and ionizing gases
以上研究结果对于超短脉冲激光放大技术研究以及超短超强脉冲激光在低密度等离子体和空气中长距离传输和聚焦研究等具有重要的实用参考价值。 - The propagation of ultrashort laser pulse in air is analyzed with mechanics analogy by considering kerr effects and free electron defocusing . the equation describing the evolution of the laser spot is derived . it is shown that long distance focusing requires large initial beam and the propagation distance is very sensitive to the initial divergence angle of the laser beam
考虑多光子电离效应和光学kerr效应，首次利用力学类比的方法研究了超短脉冲激光在电离气体中的传输，详细分析了传输距离与激光初始光斑、初始发散角以及激光功率的关系，提出了实现长距离传输的条件。
