Single crystals of neodymium-doped barium chloroapatite have been grown by the Czochralski technique and evaluated as a laser medium. Among known Nd-doped apatites, the material studied is characterized by the longest luminescence lifetime, τ=0.375 ms, and one of the largest emission cross sections, σ=6×10-19 cm2. The product στ in this crystal, which is equal to 2.3×10-22 cm2 s, is apparently the largest of those of all Nd-doped laser crystals. Laser operation at 1053.8 nm with a slope efficiency of 25% and an intrinsic slope efficiency of 49% was obtained.
