High-power and high-beam-quality with unstable resonator in a Yb:YAG slab laser.

ABSTRACT: The development and implementation of an unstable resonator laser system were explored in the present study, employing dual-end pumping of a Yb:YAG slab laser via laser diode (LD) arrays. The proposed system exhibited significant improvements in both power output and beam quality. The experimental design and execution of the laser oscillator were conducted under controlled conductive cooling conditions. Operating at a current of 90 A, the system achieved a total output power of 3823 W, with continuous-wave laser emission at 1030 nm observed bidirectionally. The measured beam qualities were 1.737 and 2.085, indicating that the system maintained good beam quality while achieving high power output. Additionally, an investigation into the optical-to-optical conversion efficiency was conducted,
