Finally the effect of refractive index gradient on the wave surface quality of laser beam is discussed.
讨论了折射率梯度对传输激光波面质量的影响和波面补偿的可能性。

When we were discussing the index of refraction we saw that an incoming beam of light will make the atoms rediate again.
在讨论折射率时，我们曾看到入射光束使原子再辐射。

Based on the matrix optics, the propagation and transformation characteristics of Gaussian beam through a parabolic gradient-index rod with the spherical end surfaces are analyzed.
