Title: Neodymium zirconate (Nd{sub 2}Zr{sub 2}O{sub 7}) transparent ceramics as a solid state laser material

Abstract

Transparent neodymium zirconate (Nd{sub 2}Zr{sub 2}O{sub 7}) ceramics have been fabricated from nanoparticles prepared by combustion synthesis. Emission at 1054.5 nm has been demonstrated using a laser diode pump at 800 nm. A transmittance of 60% at wavelengths longer than {approx}900 nm was achieved. A consequence of the very high concentration of Nd ions (1.32x10{sup 28} ions/m{sup 3}) is that the absorption bands are wider than those of Nd doped Y{sub 3}Al{sub 5}O{sub 12} (Nd:YAG) facilitating pumping over a broader range of wavelengths. The full width at half maximum of the emission peak is also larger than that of Nd:YAG, and the decay time is 460 {mu}s making Nd{sub 2}Zr{sub 2}O{sub 7} an excellent candidate for efficient high-power microchip lasers emitting at 1054 nm with diode pumping at {approx}800 or {approx}900 nm.
