光束质量标准中传输方程的研究

STUDY ON THE BEAM PROPAGATION EQUATION IN ISO STANDARD DRAFT OF BEAM QUALITY

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。

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.
