  • Automated AC filament universal laser power controller in a gas ion laser system and method
    Patent number: 6310901
    Abstract: A power supply is provided for use in a laser system including a gas ion laser tube which requires a filament voltage provided by an output section of the power supply. The filament voltage provided should not exceed a maximum AC filament voltage specified for the laser tube. The power supply is configured to receive AC utility power using one of at least first and second AC utility power sources having different first and second intended fixed magnitudes and which utility sources vary in amplitude from the intended fixed magnitudes over corresponding first and second source voltage ranges. The power supply is configured to include a power control arrangement which automatically controls the output section to generate an auto-ranging AC filament voltage from either of the first and second utility sources to be supplied as the filament voltage.
