Abstract :
Summary form only given. The authors show that the pump absorption decreases linearly with dopant concentration and, therefore, lowering the concentrations for Nd:YVO/sub 4/ crystals extends the fracture-limited pump power. They determine the optimum dopant concentration for Nd:YVO/sub 4/ crystals in scaling to higher power in a end-pumped geometry.
