Abstract

We report on fabrication and characterization of channel waveguide lasers, operating near 1.06 micrometers and made in a commercial neodymium-doped glass using thermal silver ion exchange. The slope efficiency and threshold are measured as a function of waveguide width. The waveguide structure with a 7.5 micrometers width shows the best laser characteristics in terms of threshold and slope efficiency. The emitted wavelength, while close to the peak emission wavelength of the bulk glass at 1.059 micrometers , varies with the waveguide width. This behavior is interpreted in terms of the birefringence and the dichroism of the waveguides.
