  • Systems for generating high-power short-pulse laser light
    Patent number: 7072367
    Abstract: A method for generating ultra-short pulse amplified Raman laser light. Short pulse laser light is amplified, and a portion thereof is introduced into a Raman oscillator to produce compressed laser light. The compressed light is introduced to a first Raman amplifier. The remainder of the short pulse laser light is introduced to a polarizer, and the reflected light is introduced into the first Raman amplifier to pump it. The light transmitted through the first Raman amplifier that has not contributed to pumping is introduced to a beam splitter to produce a second reflected light that is passed to a second Raman amplifier to pump that amplifier. The compressed light is amplified in the first Raman amplifier and introduced to the second Raman amplifier to further amplify it. This further amplified radiation is passed through delay lines to the beam splitter, which passes only first Stokes radiation to generate ultra-short pulse amplified Raman laser light.

  • Method of processing substances by short-pulse, wavelength tunable raman laser
    Patent number: 6906283
    Abstract: Short-pulse Raman laser is used to perform precision working of a substance without causing thermal effects on it or examine the interior of the skin or process the interior of a transparent material such as glass. By typically choosing a suitable Raman medium to be illuminated with a pump laser, the short-pulse Raman laser can have a wavelength that matches the wavelength of absorption by the substance of interest.
