| Abstract: | Used birefringent effects of uniaxial crystal and the interference principle of polarized light, a birefringent filter which contained four plates of quartz crystalline is designed, and the principle of filtering and the parameters characters of birefringent are analyzed. The transmission curve of birefringent filter is given experimentally. Its transmission bandwidth is very narrow and all the sub-peaks are suppressed fewer than 10%. When used in pulsed laser, there is broad-tunable range of 450nm. The line width range is 5nm when used F-P interferometer to compress. |
