法国LULI实验室将自适应光学与准直系统结合有效地校正了高峰值功率激光器的波前像差,获得了近衍射极限的光斑,且通过啁啾脉冲放大技术可达到拍瓦量级。该激光系统能发射波长1053nm,脉冲宽度纳秒量级,脉冲能量千焦耳的激光束。他们根据像差产生的原因将其分为三类:一是光学元件及光束失调产生的静态像差;二是热沉不均匀性导致的热致像差;三 France LULI Laboratory will be adaptive optical and collimation system combined with effective correction of the high peak power laser wavefront aberration obtained nearly diffraction limited spot, and through the chirped pulse amplification technology can reach the watt-watt order. The laser system emits a laser beam with a wavelength of 1053 nm, a pulse width of nanoseconds, and a pulse energy of one thousand joules. They are divided into three categories according to the causes of aberrations: one is the static aberration caused by the optical element and the beam misalignment; the other is the thermal aberration caused by the nonuniformity of the heat sink; the three
