The Nd:YAG nanopowders were synthesized at 800–1300°C via a modified co-precipitation method. Nd:YAG transparent ceramics were fabricated by vacuum sintering at 1770–1790°C for 20h with heating rates 1–10°C/min. The effects of calcining temperatures of highly sinterable Nd:YAG nanopowders, sintering temperature and heating rate on microstructure and transmittance of Nd:YAG ceramics have been investigated...
LIDAR techniques have been extensively used for studies of aerosol particles. Fluorescence LIDAR was employed for studying natural bio aerosols, such as pollen, but also possible warfare agents. Insects, being "large aerosol" particles clearly give rise to LIDAR returns. Recently, honey bees were studied by polarization reflectance LIDAR and their superior olfactory abilities were used in...
