We demonstrate that double-clad waveguides can be used to obtain multiWatt, CW and Q-switched, diffraction-limited output when end-pumped by broad-stripe diodes. The waveguide geometry is shown to be especially favourable for efficient laser operation of low gain and quasithree-level transitions. The performance of the Nd:YAG system at several operating wavelengths. The quasithree-level 946 nm performance appears particularly impressive. The passively Q-switched Yb:YAG double-clad waveguide laser is demonstrated.
