Abstract
Apparatus for producing laser radiation substantially at 1,444 .mu.m. Embodiments of the present invention are improved structures for neodymium lasers wherein an active laser material is formed in the shape of a rod, a tube, and a slab, including embodiments of a slab laser wherein the slab is pumped by diode arrays. In particular, the improved designs relate to the reflectivities assigned to reflectors which form the laser resonator; the structure of the pumping apparatus (including the shape and composition of the pumping cavity); the concentration of Nd; the dimensions of the active material; the structure of the laser resonator; and the pumping parameters such as pulse duration, pulse rate, and pump energy.
