Title: High energy pulse suppression method
Inventor: GRANT KEITH
IPC: H01S3/11
Filed: 2005-04-13
Abstract: A laser (126) processes a workpiece (120) with laser pulses (192) delivered at random time intervals and at substantially constant energy levels by characterizing the laser cavity discharge behavior and utilizing that information for adjusting dummy pulse time periods to compensate for the energy errors. Dummy pulses (194) are laser pulses that are blocked from reaching a workpiece. A second way for providing constant pulse energies employs an AOM (10) for varying amounts of laser energy passed to the workpiece. A third way of providing constant pulse energies entails extending the pulse period (200) of selected pulses to allow additional laser cavity charging time whenever a dummy pulse is initiated.
