    摘要： A laser chamber has angled reflectors that reflect acoustic and shock waves away from the laser discharge area to minimize acoustic and shock wave disturbances. The angled reflector may have different configurations to assist in the dissipation of the acoustic and shock waves. For example, the angled reflector may have a modulated reflective surface, such as having grooves or holes defined within the surface. Further, the angled reflector may have a reflective surface with acoustic and shock wave absorbing properties. The reflective surface with absorbent properties may be a felt metal or have multiple layered porous surfaces. In addition, the walls of the laser chamber may be modulated to assist in the dissipation of the acoustic waves and shock waves through absorption, scattering, and by generating interference within the reflected waves. Multiple layered porous surfaces may be used along the walls to absorb and scatter incident waves. The walls of the laser chamber may also be covered with an acoustic and shock wave absorbing material, such as felt metal. In other embodiments, the walls of the laser chamber are modulated with grooves, such as triangular or rectangular horizontal grooves, which scatter incident waves and generate interference within reflected waves.

    摘要翻译： 激光室具有倾斜的反射器，其将声波和冲击波反射离开激光放电区域，以最小化声波和冲击波干扰。 成角度的反射器可以具有不同的构造以辅助声波和冲击波的消散。 例如，成角度的反射器可以具有调制的反射表面，例如在表面内限定有凹槽或孔。 此外，成角度的反射器可以具有具有声波和冲击波吸收特性的反射表面。 具有吸收性能的反射表面可以是毡状金属或具有多层多孔表面。 此外，可以调制激光室的壁，以通过吸收，散射和在反射波内产生干涉来帮助消除声波和冲击波。 沿着壁可以使用多层多孔表面来吸收和散射入射波。 激光室的壁也可以用诸如毛毡金属的声波和冲击波吸收材料覆盖。 在其他实施例中，激光室的壁由诸如三角形或矩形水平凹槽的凹槽调制，这些凹槽散射入射波并在反射波内产生干涉。
