Abstract

The evaluation of pump capability and scaling output power of vanadate lasers are presented in this paper. With the consideration of thermal fracture limitation and fundamental mode operation, systematic investigations of vanadate crystals are conducted to scale the output power of diode-end-pumped lasers to higher levels. Based on the limitation of pump power, the input-output characteristics and beam propagation factor of vanadate lasers are optimized with the knowledge of thermal effects. The theoretical analyses provide a good prediction to the experiment. A practical example of a single endpumped vanadate laser is demonstrated with cw output powers of 9.8W in TEM00 mode and 12.4W in multimode.
