高功率laser脉冲的引力影响
Gravitational influence of high power laser pulses
摘要：
在实验室中研究度规微扰的产生提供了一个更容易观察和理解引力作用机制的机会。目前的研究将集中在由光脉冲产生的度量扰动，因为它可以由当前的超高功率激光器产生。虽然是非常小的幅度，这样产生的潜在的优势，产生的质量加速度，如没有噪音，由于不均匀的加速度或扩大实验的能力。与机械振荡器相比，电磁振荡器确实更容易放大，机械振荡器必须具有大的加速质量或许多小质量，所有这些都同步，而且加速必须是四极的。因此，用激光产生米制形变，可以证明对长期建立产生和探测引力波的实验室实验是有用的。
英文摘要：
The study of the generation of metric perturbation in the laboratory presents an opportunity to observe and understand more easily the mechanisms at work in gravitation. The present study will focus on the metric perturbation generated by a light pulse, as it could be generated by a current ultra-high power laser. Although of very small magnitude, the potential thus generated has advantages over that generated by mass acceleration, such as the absence of noise due to non uniform acceleration or the ability to scale up the experiment. It is indeed easier to scale up an electromagnetic oscillation compared to a mechanical oscillator, which must either be made with a large accelerated mass or a lot of small masses, all in sync, which acceleration must furthermore be quadripolar. Generation of metric deformation by laser could therefore prove useful in the long-term establishment of a laboratory experiment for the generation and detection of gravitational waves.
