Ion-exchanged Er/Yb waveguide laser at 1.5µm pumped by a laser diode
We demonstrate a diode-pumped, planar Er/Yb waveguide laser. The device was fabricated by thallium exchange in a phosphorus-free silicate glass. Lasing was achieved at 1544 nm with a threshold of 5 mW and a slope efficiency of 2%. The low threshold indicates the absence of the severe backtransfer ef...
