Abstract:
Zero-order diffractive elements have particular properties that provide for their advanced application in optical systems with high-power lasers. This paper presents the results of a theoretical and experimental study of a new class of zero-order diffractive elements - variable-density filters of optical radiation. The paper presents the results of testing the circular diffraction filters with amplitude and phase transmission function. It discusses the production methods and provides characteristics of experimental samples. It demonstrates that phase filters allow to control the radiation of high-power pulse lasers and continuous-wave lasers, these filters are insensitive to polarization, and have a large dynamic range.
