Abstract:

The results of investigations of mechanical, optical and laser characteristics of ceramics made from neodymium-activated yttrium oxide are presented. The ceramics were fabricated with the use of a new technology including Laser synthesis of nanopowders and their magnetic pulsed compaction (LSN\&MPC). The fracture toughness (K-IC = 0.9-1.4 MPa m(1/2)) and microhardness (H-v = 11.8 GPa) of the ceramics have been determined. It has been found that ceramic samples sintered in the temperature range from 1550 to 2050 degrees C have (1-150) vol. ppm porosity and optical loss coefficient in the range from 0.03 to 2.1 cm(-1). It has been shown that pore content in this range did not influence on the optical loss coefficient. Laser generation at lambda(g) approximate to 1.079 mu m with a slope efficiency of 15\% under laser diode pumping has been obtained in 1.1 mm thickness sample with alpha(1.07)mu m = 0.03 cm(-1).
