Abstract
We report the laser performance of a short diffusion-bonded diode-pumped Yb :YAG rectangular channel waveguide of 100 mum cross section. Using an end-p umped configuration guiding only the slow axis, a high overlap of the pump mode and the nonguided resonator mode is achieved. With 4 W of pump power f rom two 60 mum high-power broad-stripe diodes, 0.7 W of output power with n early diffraction-limited performance is obtained. (C) 2000 American Instit ute of Physics.
