Abstract
There is described a method of and apparatus for regulating the output power of lasers of the type utilizing a heated high velocity flowing gas. The method and apparatus comprise a plurality of separate sources of the gas in combination with a segmented diffuser section wherein at least one but not all of the diffuser sections can be blocked to selectively permit use of all or less than all of the gas sources, thereby permitting regulation of output power by regulating the mass flow through the optically resonant cavity disposed between the sources of gas and the diffuser.
