摘要
本文利用重铬酸盐明股作为记录介质,采用双曝光记录工艺,试制了反射式双峰值波长的全息滤光片.这种全息滤光片双峰值衍射效率可达87%,带宽小于10nm,是一种新的具有潜在应用前景的全息光学元件.
The holographic gratings using DCG recordings material have the advantages of highdiffractive efficiency and low noise. Thanks to its significant Bragg diffractive effects, the reflectiveholographic gratings are much sensitive to the wavelength change, thus available for multi-exposiverecordings. In view of this, bi-peak value narrow band width holographic filter is studied using thedouble exposure recordings and special redeveloping techniques. This type of filter is comparativelyhigh in diffractive efficiency with bi-peak wave length at the same angle, and its peak value efficiencycan reach 87% and the band width is less than 10um, this filter has a wide and potential application inholographic image and light communications. This paper presents a discussion and analysis on thefilter's development and its spectrum features also.
