Pulsed laser using a moving intracavity photon deflector as a beam extractor

Abstract

A pulsed laser utilizing an oscillating or rotating intra cavity photon deflector means to extract a beam transverse to the long axis of the resonator from intracavity power. The moving photon deflector is supported and set into motion either mechanically or electromagnetically within the resonator and in the path of lasing photons, thereby intercepting and deflecting photons out of the resonator. Movement of the deflector within the path of lasing photons results in the circumferential deflection of photons with the most intense concentration being deflected from that portion of the surface of the deflector which first intercepts the circulating intracavity photon stream. As lasing photons are deflected from the leading edge of the deflector, lasing action is instantaneously reestablished after the trailing edge moves through the photon stream. Wherever the deflector does not intersect the normal trajectory of photons in the laser cavity, lasing action is automatically reestablished. The invention can be incorporated with both open and closed cavity laser designs.
