Abstract
A method of operating a q-switch RE,XAB laser includes: providing a pump bias current to a pump source, the pump source directed to an RE:XAB gain medium, the RE:XAB gain medium within a resonator cavity, where X is selected from Ca, Lu, Yb, Nd, Sm, Eu, Gd, Ga, Tb, Dy, Ho, Er, and where RE is selected from Lu, Y, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Pr, Tm, Cr, Ho, with a bias current level below a lasing threshold of the RE:XAB gain medium; providing a pump pulse to the gain medium, the pump pulse of the lasing threshold of the RE:XAB gain medium, the pump pulse causing the RE:XAB gain medium to emit a laser pulse; and reducing the pump bias current to at least below the gain medium lasing threshold, the combination of the pump bias, the pump pulse, and the pump reduction having a current profile.
