Paper Abstract

We report on the realization and analysis of a 150 W peak-power passively Q-switched Yb-doped double-clad fiber laser with 30 μJ pulse energy, and 205 ns pulse duration using Cr4+:YAG saturable absorber. Analysis of the effect of mode area inside the saturable absorber on pulse characteristics has also been carried out.
