Abstract
In this letter, numerical simulation and experimental study of a radial-slab solid-state
laser are presented. The laser includes four crossing-slabs pumped by four Xe flashlamps. The
numerical simulation of coherent intensity in the near field and the far field indicates that the
laser with the structure can improve the quality of output beam compared with incoherent beam
combination. The radial-slab solid-state laser is fabricated, and initial experiments are carried
out at a pulse repetition of 1 Hz. Nine beams in the near field and one combined beam in the far
field are obtained in our initial experiment. The experimental results are consistent with the
numerical analysis in the coherent condition. The results show that coherent beam combination is
obtained by this laser.
