Experimental Study of Nd³⁺:KGd(WO₄)₂ Laser Pumped by Laser Diode

This paper presents the cw output characteristics of Nd³⁺:KGd(WO₄)₂ (KGW) laser crystal with different Nd³⁺ concentration grown in our laboratory. The laser output at 1.067μm of KGW crystal (3x3x6mm) was obtained to be 68.9mW and the slope efficiency reached 28.8% when pumped by laser diode of power 305mW at 807nm.
