Abstract
The realization of diode-pumped waveguide amplifiers and lasers based on highly doped epitaxial layers is reported. An original single-diode-bar face-pumping configuration is used. The propagation losses are, respectively, lower than 0.3 and for 12% and 24% Yb-doped waveguides. The amplifiers provide up to net amplification at , with spatially single-mode output. Monolithic waveguide lasers exhibited 14% slope efficiency, with output power at .
