The advantages and potential hazards of using a planar waveguide as the host in a high-power diode-pumped laser system are described. The techniques discussed include the use of proximity-coupled diodes, double-clad waveguides, unstable resonators, t

We report on the design and fabrication of Nd:YAG planar waveguides suitable for in-plane, diode-bar pumping. Contact-bonded Nd:YAG on Sapphire waveguides are shown to have the high numerical aperture (0.46), low propagation loss (

Greater than 12 W of average output power has been generated from a diode-pumped Yb:YAG cladding-pumped planar waveguide laser. The laser radiation developed is linearly polarized and diffraction limited in the guiding dimension. A slope efficiency o

A new technique for fabricating active planar waveguide devices is reported. This process, based on the thermal bonding of precision finished crystal or glass components, allows waveguides to be assembled from very dissimilar materials and could be a

Summary form only given. Recent work on high-power, planar waveguide lasers has been motivated by the fact that the planar geometry is ideal for thermal management and well-matched to that of diode-bar pump lasers, previously allowing simple cylindri

Summary form only given. The use of a double-clad guiding structure to allow efficient pumping by non-diffraction-limited high-power diodes, and yet still obtain diffraction-limited laser output, has been extensively studied in optical fibres. Recent

We report the demonstration of a near-diffraction-limited, compact, diode-end-pumped double-clad planar waveguide Nd:YAG laser. Efficient laser operation was achieved for the three dominant Nd(3+) transitions, at 1.064, 0.946, and 1.32microm , with T

The high-power side-pumped operation of a double-clad Tm:YAG waveguide laser at 2.02 /spl mu/m, using two proximity-coupled 20 W diode pump lasers, is reported. A slope efficiency of 43% was observed with respect to incident diode power, giving a max

We have experimentally determined loss coefficients of OH as 8.1 × 10−7 cm−1 / ppm and of ionic platinum as 8.6 × 10−7-7cm−1/ppm for LHG-5 type phosphate laser glass without Nd2O3 doping. Glass has been produced with absorption loss of abou
