  • Laser system providing power ramp-up and method of operating same
    Patent number: 6115397
    Abstract: In a laser system which produces radiation which is highly absorbed by water, the pump voltage supplied to the laser rod is slowly increased between the lasing threshold voltage and the full operational voltage of the pump. As a result, the output energy and circulating energy of the system slowly increase, such that any water on the intracavity coatings is vaporized slowly, rather than explosively. The laser system and method of using same thus reduce or prevent damage to the intracavity coatings used within the laser cavity.

  • Optical filtering element and a spectral refining device including the same
    Patent number: 4490021
    Abstract: A filtering element for a beam of coherent light, comprising a diffraction grating placed in the path of the beam and disposed with respect to the direction of the beam in such manner that the angle of incidence of the beam is at least equal to 80.degree. and different from the angle of diffraction. At least one additional optical element is placed in the path of a component of the beam diffracted by said grating for returning to the grating a part of the light of said component.
