Abstract
Spectral and pulsed laser properties of Nd3+ : YAlO3 crystals codopes with Cr3+ are described. The anisotropic properties of yttrium orthoaluminate were used to select a laser rod orientation which maximized the energy storage capability for Q‐switched operation. It is demonstrated that a c‐axis rod of this material can produce energy outputs greater than those obtainable from the best Nd3+ : YAG rods of comparable size in both long‐pulse and Q‐switched laser operation.
