  • Q-switched laser
    Patent number: 6778563
    Abstract: A microchip laser arrangement is disclosed. The arrangement is operative to emit Q-switched laser pulses at 1.54 &mgr;m. The lasing medium of the laser arrangement is preferably comprised of Yb:Er-glass, and the Q-switch is comprised of a saturable absorber of cobalt doped spinel crystal. The lasing medium is preferably bonded to the absorber to form a monolithic body, upon the surface of which there are deposited dielectric stacks forming a resonant laser cavity. Pumping of the active medium is performed by means of an InGaAs laser diode emitting light at 0.97 &mgr;m, corresponding well with the absorption of the Yb:Er-glass material.
    Type: Grant
    Filed: June 5, 2001
    Date of Patent: August 17, 2004
    Assignee: Cobolt AB
    Inventors: Fredrik Laurell, Valdas Pasiskevicius, Boris Ivanovic Galagan, Gunnar Karlsson, Boris Ilich Denker, Sergei Evgenievich Sverchkov
