Abstract : This invention is directed to a power amplifier system which extracts high power optical radiation from a laser media. The system includes a gas dynamic, E-beam, or chemical laser from which power is extracted. The extracted power is as near diffraction limited as can be attained from the active media at the highest power possible while maintaining the beam quality of the laser radiation. A mirror reflection system reflects a laser beam through a laser media four or more times by use of appropriate mirrors. Each time the laser beam traverses the laser media, the output power is amplified until the finally reflected beam is directed to a target. Between the first and second pass along the length of the laser media the beam is flipped over by the mirrors to produce the same effect on the laser beam especially when a gas flow type laser is used.
