Fabrication and thermal effects of highly transparent polycrystalline Nd:YAG ceramics
چکیده انگلیسی


• Highly transparent Nd:YAG ceramics were fabricated by solid-state reactive sintering.
• The in-line transmittance of Nd:YAG transparent ceramics reaches 83.9% at 1064 nm.
• The thermal effects in the Nd:YAG ceramics were mainly investigated.

Highly transparent polycrystalline 2.0 at.% Nd:YAG ceramics were fabricated by a solid-state reactive sintering method using commercial α-Al2O3, Y2O3 and Nd2O3 powders as starting materials. The in-line transmittances of the Nd:YAG ceramics vacuum sintered at 1750 °C for 50 h with the thickness of 5.8 mm are 83.9% at 1064 nm and 82.5% at 400 nm. The thermal effects in the Nd:YAG ceramics were mainly investigated in detail. It is found that the thermal focal length decreases with the increase of pump power. The experimental results of thermal focal lengths are in accordance with the theoretical calculations. The observed depolarized beam patterns and depolarization phenomena illustrate the detailed change of thermally induced birefringence in Nd:YAG ceramics. The depolarization shows a obvious nonlinear change tendency at low pump power.
