Abstract:

We studied mechanical, optical, and lasing parameters of neodymium-doped yttrium oxide ceramics synthesised by using a new technology involving the laser synthesis of nanopowders and their magnetic pulsed compaction. The fracture toughness of ceramics to cracks and its microhardness were measured to be K-IC = 0.9 - 1.4 MPa m(1/2) and H-v = 11.8 GPa, respectively. Ceramic samples sintered in the temperature range from 1550 to 2050 degrees C have the porosity (1 - 150) x 10(-4) \% and the optical loss coefficient alpha(1.07) = 0.03 - 2.1 cm(-1) at a wavelength of 1.07 mu m. It is shown that such porosity does not affect the optical loss coefficient of fight. Lasing at similar to 1.079 mu m with a slope efficiency of 15\% was obtained in a 1.1-mm-thick sample pumped by laser diodes.
