Abstract

We report on passively Q-switched operation of a diode-pumped Er–Yb:glass laser with a Co2+:MgAl2O4 plate as a saturable absorber. Optical pulses with peak power exceeding 2 kW and a pulse length of 2.3 ns have been generated. Single-longitudinal-mode Q-switched operation at 1.53 µm has been obtained by use of the Co2+:MgAl2O4 plate as an intracavity etalon. A discussion of the optimal Er3+ concentration as well as optimization of the cavity design is included.

Measured output-power dependence on pump power in cw Er–Yb:glass lasers. The doping densities are N Er = 1 × 1020 cm-3 (circles) and N Er = 2.5 × 1020 cm-3 (triangles). Solid curves, numerical calculations using Gaussian intensity distributions for the laser mode and the pump. Dashed lines, calculations assuming top-hat profiles for the laser and the pump beams; i.e., the reabsorption losses at the mode edges are disregarded.

Output spectra (solid curves) and the temporal waveforms (insets) measured for the laser configuration with (a) the Co2+:MALO plate coated as an output coupler, at the pump power at which repetition-rate doubling occurs, and (b) the Co2+:MALO plate used as an intracavity etalon at the maximum pump power. Dashed curves, cavity modes. In (b), the lasing wavelength, λ0, is centered at 1535 nm.
