20090238222 | LASER SYSTEM EMPLOYING HARMONIC GENERATION - A laser system provides harmonic generation in a laser beam pulse. In another aspect of the present invention, a laser operably remits a laser pulse, a gaseous optical medium operably creates third or greater harmonic generation in the pulse, and a controller characterizes and compensates for distortions in the pulse. A further aspect of the present invention employs multiple optical media arranged to cause cascading harmonic generations in a laser pulse. | 2009-09-24 |
