光束质量标准中传输方程的研究
-
摘要: 讨论了传输方程在ISO光束质量标准中的重要性，给出了光束传输方程的一种证明方法，在近轴条件下，非高斯光束都满足传输方程，这为选用理想高斯光束作为光束质量的度量基准奠定了基础。Abstract: In the paper, the importance of the beam propagation equation in ISO standard draft is discussed, and a verifying method is given. The beam propagation equation is applied to not only Gaussian beam but also the other non –Gaussian beam on the paraxial condition, and it lays the foundation for Gaussian beam to become the measured standard of beam quality.
