✦ Synopsis

In this paper we report on the characterization of a diode-side-pumped Nd:YAG rod laser operating at 300 W CW output power. The simulated and measured pump energy distributions in the crystal are compared. The thermal lens effect of the Nd:YAG have been experimentally investigated, and its influence on the performance of the laser are discussed. Output power and the beam quality of the laser under different resonator mirrors and rod end-face curvatures have been experimentally studied. The optical-to-optical and electrical-to-optical efficiencies are 28.5% and 11%, respectively. The beam parameter product is 40 mm⋅mrad and the instability of laser is about 3%.

## Abstract The use of the CO~2~ laser in liver surgery is mainly limited by the lack of coagulation of the larger vessels. In an experimental study, partial liver resections were performed on pigs with a Nd:YAG as well as with a combined CO~2~ and Nd: YAG laser. The best cutting efficiency was obt
