Paper Abstract

High power diode-pumped planar waveguide Nd:YAG lasers with good output beam qualities are demonstrated with gain control technique. Around 100 W output power with nearly diffraction-limited beam quality is achieved by asymmetric edge-pumping and negative branch confocal unstable resonator. A miniature Nd:glass slab laser and a Nd-glass belt laser are also demonstrated. The beam quality in the Nd-glass belt laser is improved by V-groove pairs scribed on the edges of the Nd:glass belt.
