英文摘要	For a laser (2) capable of continuous wave operation, a power supply (4) for supplying pulsed power to the laser includes circuitry (76, 78) for modulating the power supplied to the laser in order to generate a pulsed laser output beam. The pulsed operating mode reduces the amount of heat generated during system operation, so that the system may be cooled by an internal. self-contained coolant flow loop. An independent safety monitoring system (46, 54) is capable of terminating tbe laser output in response to any unsafe failure of the control system. An argon laser tube (2) capable of generating between 6 and 7 kilowatts of heat at full continuous wave power generates only 2.5 kilowatts of average power during the electronically pulsed operating mode. A power supply control board (76) controlled by microprocessor based control electronics (6) and the safety monitor (54) controls a tube pulse starter (82) and a power MOSFET pass bank (78) connected in series with the laser tube (2).
