Abstract

We demonstrate comparative studies for Cr⁴⁺:YAG crystal and AlGaInAs quantum-well (QW) used as a saturable absorbers in passively Qswitched Yb-doped fiber lasers. Both saturable absorbers were designed to be possessed of nearly the same initial transmission. Under a pump power of 24 W, the average output powers were up to 14.4 W and 13.8 W obtained with the AlGaInAs QWs and with the Cr⁴⁺:YAG crystal, respectively. The maximum pulse energies obtained with the Cr⁴⁺:YAG crystal and with the AlGalnAs QWs were found to be 0.35 mJ and 0.45 mJ, respectively.
