| Abstract: | A Raman filter with double transmission gratings was designed. The band of the filter covered from 480.0 nm to 650.0nm. A Stray-Light discrimination of less 10-8 at 30 cm-1 from the parent line( 632.8 nm) was achieved. The transmissivity was over 4%. Some possible applications and improving envisagements of the filter were discussed. |
