摘要：

1.5 at.% Nd:Y1.8La0.2O3 transparent ceramic was fabricated by a solid-state reaction method and sintered at 1650-1700 degrees C for 40-50 h under H-2 atmosphere. The spectroscopic properties were investigated at room temperature. The transparent ceramic has excellent spectroscopic properties, with the absorption cross section of 1.50 x 10(-20) cm(2) and broad full width at half maximum (FWHM) of about 8 nm at LD wavelength 806 nm, the emission cross section of 2.03 x 10(-20) cm(2) at 1079 nm, and the decay lifetime of 200 mu s. Laser performance was carried out using an uncoated Nd:Y1.8La0.2O3 ceramic plate under laser diode end-pumping without any water cooling device. The room temperature thermal conductivity of this ceramic is 6.20 W/mK. For Nd:Y1.8La0.2O3 ceramic laser, a maximum output power of 62 mW was obtained at 1079 nm under a 808 nm diode pump.
