  • High average power ultra-short pulsed laser based on an optical amplification system
    Publication number: 20090273828
    Abstract: The present invention includes an apparatus and the method to scale the average power from high power ultra-short pulsed lasers, while at the same time addressing the issue of effective beam delivery and ablation, by use of an optical amplification system.
    Type: Application

  • Methods for optical isolation in high power fiber-optic systems
    Patent number: 7433558
    Abstract: Methods for optical isolation in high peak power fiber-optic systems prevent damage to a facet within a fiber-optic isolator caused by back-reflected light from, for example, an optical amplifier. Preventing damage to the facet may include expanding a mode area of the back-reflected light and/or reducing a change in refractive index.

  • Wavelength-stabilized pump diodes for pumping gain media in an ultrashort pulsed laser system
    Patent number: 7245419
    Abstract: In an optical amplifier, passively wavelength-stabilized pump diodes generate pumping light to excite a gain medium (e.g., rare-earth-ion doped optical fiber or solid-state optical amplifier) near an absorption peak of the gain medium. The gain medium amplifies a pulsed laser signal coupled into the gain medium to a high peak power with minimal non-linear distortion. The gain medium may include a portion configured to receive the pumping light and another portion configured to amplify the pulsed laser signal. A volume phase hologram device may passively wavelength stabilize the pump diodes by reflecting a portion of the pumping light back to the pump diodes. Passively wavelength-stabilizing the pump diodes improves power efficiency of the optical amplifier.
