为了抑制横向受激拉曼散射（TSRS），在大口径KDP晶体中产生了由多个针尖组成的激光损伤阵列。36 cm x 8.5 mm x 7 mm损伤阵列用于阻挡晶体内TSRS光子的传播并减小TSRS增益长度。在大口径激光系统上进行了一系列实验，实验结果表明，激光损伤阵列对TSRS的放大有明显的抑制作用。(C)2013年美国光学学会
A laser-induced damage array composed of numerous pinpoints is generated in a large-aperture KDP crystal to suppress the transverse stimulated Raman scattering (TSRS). The 36 cm x 8.5 mm x 7 mm damage array is used to block the propagation of the TSRS photons within the crystal and decrease the TSRS gain length. Then several series of experiments were conducted on a large-aperture laser system to test this method and experimental results show that the amplification of TSRS is significantly suppressed by the laser-induced damage array.
