摘要
一束异常偏振的Ar+激光束(λ=488 nm,I=3.4 W/cm2)斜入射到一块沿主坐标轴切割的Cu掺杂的钾钠铌酸锶钡(KNSBN)晶体上,在后面的观察屏上,观察到一种新型的各向异性散射环,同时还出现了强烈的非对称扇形效应和非对称各向同性及向向异性锥形散射以及法线方向的各向同性散射振荡,理论分析表明前者由后者引起的,且理论值和实测值吻合得非常好.
Abstract
A new type of anisotropic scattering rings and the isotropic scattering oscillation are observed on a screen behind a Cu:KNSBN crystal pumped by an extraordinary beam. The latter plays a key role in the forming of the former.
