Experimental and theoretical study of finite-aperture tapered unstable resonator lasers

摘要

We present experimental and theoretical results of a novel finite-aperture tapered unstable resonator laser under pulsed and CW operations. At a current of 16 A an output power of about 10W is reached. The beam parameter increases from M~2 ≈ 10 at P = 1W to M~2 ≈20 at P = 10W. Spatial-temporal simulations were performed to elucidate this experimental finding.
