ABSTRACT
We report the laser performance of a short diffusion-bonded diode-pumped Yb:YAG rectangular channel waveguide of 100 μm cross section. Using an end-pumped 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 from two 60 μm high-power broad-stripe diodes, 0.7 W of output power with nearly diffraction-limited performance is obtained. © 2000 American Institute of Physics.

    It is shown that bond contraction and nonbonding lone-pair interaction dominate at nitride surfaces. The maximum elastic recovery of a nitride surface was found to be 100% under a relatively lower nanoindentation load (<1.0 mN) and the hardness of the surface was found to be 100% higher than the...
