Spatial filter for high power laser beam |
摘要 |
<p>The invention comprises a spatial filter and a method of spatially filtering a laser beam, particularly a high power laser beam. High spatial frequency light is nonabsorptively diverted away from low spatial frequencies. The invention provides a method of writing gratings in optical waveguide fiber that results in improved grating performance. <IMAGE></p> |
