Paper Abstract

The results of investigations of mechanical, optical and laser characteristics of ceramics made from neodymiumactivated yttrium oxide are presented. The ceramics was fabricated with the use of a new technology including Laser synthesis of nanopowders and their magnetic pulsed compaction (LSN&MPC). The fracture toughness ΚIC = 0,9 - 1,4 MPa•m1/2) and microhardness (HV = 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°C have (1 - 150) vol. ppm porosity and optical loss coefficient α1,07 μm = 0,03 - 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 λg ≈ 1,08 μm with a slope efficiency of 15 % at laser diode pumping has been obtained in 1.1 mm thickness sample with α1,07 μm = 0,03 cm-1.
