Phase retarder in chemical oxygen-iodine laser at 45° incidence

A phase retarder used in chemical oxygen-iodine laser （COIL） system has been fabricated by ion beam sputtering （IBS）. When the incident angle is 45°the reflectivity is about 99.9% from 1290 to 1340 nm and about 83.8% at 632.8 nm, and the phase retardance between the parallel and perpendicular polari...

Description
Summary:A phase retarder used in chemical oxygen-iodine laser （COIL） system has been fabricated by ion beam sputtering （IBS）. When the incident angle is 45°the reflectivity is about 99.9% from 1290 to 1340 nm and about 83.8% at 632.8 nm, and the phase retardance between the parallel and perpendicular polarization components is -92.8°at 1315 nm. In order to get the influence of temperature on the phase retarder, six samples have been annealed from 523 to 648 K at interval of 25 K in air respectively, and the results show good temperature performance, With increasing temperature phase retardance becomes smaller, and the variation is within 4° at 1315 nm. At the same time, the variation maintains within ±10° for the incidence from 44°to 49°.
