1.9-microm operation of a Tm:lead germanate glass waveguide laser.
We report what we believe to be the first planar-technology waveguide laser in the 2-microm region. Laser operation of the (3)H(4) to (3)H(6) transition of Tm(3+) ions in a lead germanate glass host has been observed in an ion-implanted planar waveguide.
