Abstract

A novel configuration for a multirod solid-state laser system is proposed. We stabilize the thermal-lens-dependent variation in the output-beam parameters by extracting the laser beam from the collimating point of periodic beam propagation. The performance is confirmed with a 100-W class diode-pumped Nd:YAG laser-amplifier system to demonstrate tenfold stabilization of the output-beam diameter.
