SOLID STATE LASER APPARATUS WITH AUXILIARY INTRA-CAVITY MIRROR ELEMENTS

A pair of intra-cavity auxiliary mirror elements are mounted at opposite ends of a laser rod. The mirror elements are provided with a central aperture to pass the main laser beam and with reflecting surfaces facing the cavity mirror to intercept and recover and stray light rays that result from ther...

Zusammenfassung:A pair of intra-cavity auxiliary mirror elements are mounted at opposite ends of a laser rod. The mirror elements are provided with a central aperture to pass the main laser beam and with reflecting surfaces facing the cavity mirror to intercept and recover and stray light rays that result from thermal focusing effects in the laser rod when it is flashed at high repetition rates.
