  • Apparatus for the generation of variable duration laser pulses
    Patent number: 6842474
    Abstract: An apparatus for the generation of variable duration laser pulses comprising an optical cavity delimited by two mirrors, one of which is a total reflection mirror and the other a partial reflection mirror, and containing an active medium with an appropriate excitation system. An optical shutter capable of inducing a Q-switching mode is provided between the total reflection mirror and the active medium. The active medium is optically connected with said total reflection mirror by optical fibre sections having different lengths and may be interchanged in the optical path so as to vary the duration of the pulses emitted by the laser when it operates in the Q-switching mode.

  • Apparatus for the generation of variable duration laser pulses
    Publication number: 20030138004
    Abstract: An apparatus for the generation of variable duration laser pulses comprising an optical cavity delimited by two mirrors, one of which (7) is a total reflection mirror and the other (1) a partial reflection mirror, and containing an active medium (4) whit an appropriate excitation system. An optical shutter (2) capable of inducing a Q-switching mode is provided between the total reflection mirror (7) and the active medium (4). The active medium (4) is optically connected with said total reflection mirror (7) by means of different lengths of optical fibre section (F1, F2, Fn) that may be interchanged in the optical path to vary the duration of the pulses omitted by the laser when it operates in the Q-switching mode.
