Abstract

Q switching of a diode-pumped Nd3+:KGd(WO4)2 laser at 1.35 μm by use of cobalt-doped magnesium- and zinc-aluminosilicate glass ceramics as saturable absorbers is demonstrated. Q-switching efficiency up to 40% has been obtained. Ground-state absorption cross sections for Co2+ ions at the wavelengths of 1.35 and 1.54 μm are estimated to be (3.5–4.0) × 10-19 cm2. Bleaching relaxation times under the excitation of the 4A24T1(4F) transition of tetrahedrally coordinated Co2+ ions are of 280 ± 50 ns and 700 ± 80 ns for magnesium- and zinc-aluminosilicate glass ceramics, respectively.
