Abstract
A laser fluid control apparatus and method provide selective, precise control of the fluid supplied to the laser. The flow of the fluid to the laser can be automatically adjusted according to a selected, programmed control to provide a high volume of the fluid to the laser during initial operation of the laser for a quick warm-up of the laser and a reduced volume after the laser has warmed-up for more economical operation of the laser. Different fluid mixes can also be provided for enhancing laser performance. A control for pulsed or continuous wave laser operation can be actuated to automatically change the composition of the fluid supplied to the laser for continuous wave laser operation as compared to that for pulsed operation.
