  • Passively mode-locked pulsed fiber laser
    Patent number: 8995478
    Abstract: The device is proposed which provides mode-locked operation of a fiber laser. The principle of its operation is based on a focusing effect of Kerr lens. At high intensities of the light beam the Kerr element exhibits light focusing properties. The beam focused by the Kerr element enters a fiber core without losses thus providing an effective generation of mode-locked laser. In the preferred embodiment the Kerr element is positioned at one degree relative to a perpendicular to the beam direction.
