A reflective optical system is described that permits nearly uniform illumination of a small sphere with one or two laser beams. The primary application of this device is to studies of laser-driven implosion of small targets. Other applications include the production of plasma by optical breakdown of gases for spectroscopic studies and for optimum light collection in intensity-limited plasma diagnostics. Simple calculations show that the intensity mapping properties of this system are not excessively sensitive to variations in the radial intensity distribution nor to departures from diffraction-limited propagation in the input beams. Optical damage and the illuminated solid angle required at the focus determine the size of the device.
描述了一种反射光学系统，该系统允许用一束或两束激光束对一个小球体进行近乎均匀的照明。该装置的主要应用是研究小靶的激光驱动内爆。其他应用包括通过气体的光学击穿产生等离子体，用于光谱研究以及在强度受限的等离子体诊断中实现最佳的光收集。简单计算表明，该系统的强度映射特性对径向强度分布的变化以及输入光束偏离衍射极限传播的情况不太敏感。光学损伤和焦点处所需的照明立体角决定了该装置的尺寸。
