Abstract

Laser oscillations have been produced in large crystals of Nd3+-doped Ca5(PO4)3F (the mineral fluorapatite, whence the coined name FAP) at room temperature under both tungsten lamp and flash lamp excitation. The laser tests show that FAP:Nd crystals have four times greater gain per incident pump energy and over one and a half times greater differential (slope) energy efficiency than equal size YAG:Nd crystals. The fluorescence, excitation, and absorption spectra of FAP:Nd are partially polarized, as expected for Nd3+ substituting Ca ii sites of C1h symmetry. The fluorescence lifetime is 0.24 msec at 300°K. Laser oscillations occur at 1.0629 μ in π polarization (Ec), which has 2.6 times the gain of σ polarization (Ec).
