Abstract

A system of local rate equations combined with a ray-tracing technique is used for numerical analysis of energy storage within a Yb:Er:glass laser under diode pumping. It is shown that any pumping system could be characterized by relative pumping efficiency, which depends mainly on the pumping source parameters but only slightly on parameters of the Yb:Er:glass. Transverse pumping can ensure the storage efficiency close to the utmost value for the glass. Some simple and efficient pumping cavities are considered. A traditional end-pumping configuration with collimating lenses is considerably less efficient. Application of nonimaging optical elements such as a lens duct can effectively increase the efficiency.

Maximum attainable relative storage efficiency for a rectangular Yb:Er:glass slab, transversely pumped by collimated beams. The pumping takes place from all four lateral faces (curves 1 and 2), from two opposite faces (curve 3), and from one face, while the opposite one is assumed to be highly reflective for pumping radiation (curve 4). Curve 1 represents relative stored efficiency divided by the efficiency of pumping absorption.

The rod diameters are 1.5 mm (curve 1), 3 mm (curve 2), and 5 mm (curve 3). The pumping pulse duration is 5 ms. Both the pumping energy and the diameter of the pumping cavity correspond to an optimal cavity at 950 nm.
