METHOD AND SYSTEM FOR DAMAGE REDUCTION IN OPTICS USING SHORT PULSE PRE-EXPOSURE |
摘要 |
A method of processing an optical element includes providing the optical element. A surface region of the optical element includes one or more pre-cursors. The method also includes raster scanning a laser beam across the optical element. The laser beam comprises a plurality of laser pulses, each of the laser pulses being characterized by a pulse length less than 1 ns. The method further includes exposing the one or more pre-cursors to the laser beam and observing a light emission event from one of the one or more pre-cursors. |
