Abstract
Transparent 1at% Nd3+:Y1.9La0.1O3 ceramics were fabricated with nanopowders prepared by carbonate coprecipitation method. The powder compacts were sintered in H2 atmosphere at 1550°C for 30h. The Nd3+:Y1.9La0.1O3 ceramics display uniform grains of about 50μm and high transparency. The highest transmittance of the ceramics reaches 67%. The strongest absorption peak is in the wavelength of 820nm with absorption cross section of 2.48×10−20cm2. The absorption is still high at LD wavelength 806nm with absorption cross section of 1.78×10−20cm2 and broad full width at half maximum (FWHM) of about 6.3nm. The strongest emission peak was centered at 1078nm with large stimulated emission cross section of 9.63×10−20cm2 and broad FWHM of about 7.8nm. The broad absorption and emission bandwidth of Nd3+:Y1.9La0.1O3 transparent ceramics are favorable to achieve the miniaturized LD pumping apparatus and ultrashort modelocked pulse laser output, respectively.
