“…Solid state tunable lasers based on single crystalline medium have significantly contributed towards the development of technology necessary for active remote sensing of the atmosphere from terrestrial, airborne and space based platforms. However, many recent studies on diode-pumped solid-state lasers have focused on polycrystalline ceramic lasers because of the advantages that they have over single crystals in terms of shape, size, ease of fabrication, and control of dopant concentrations [2][3][4][5][6][7][8][9][10].…”

“…Significant strides have been made in the development of ceramic neodymium doped Yttrium Aluminum Garnet (Nd:YAG) material [2][3][4][5]. Neodymium doped Yttria (Nd:Y 2 O 3 ) is another material that has attracted considerable attention due to its lasing wavelengths and excellent thermo-mechanical properties [6][7][8][9][10][11].…”

Solid-state lasers play a significant role in providing the technology necessary for active remote sensing of the atmosphere. Neodymium doped yttria (Nd:Y 2 O 3 ) is considered to be an attractive material due to its possible lasing wavelengths of ~914 nm and ~946 nm for ozone profiling. These wavelengths when frequency tripled can generate UV light at ~305 nm and ~315 nm, which is particularly useful for ozone sensing using differential absorption lidar technique. For practical realization of space based UV transmitter technology, ceramic Nd:Y 2 O 3 material is considered to possess great potential. A plasma melting and quenching method has been developed to produce Nd 3+ doped powders for consolidation into Nd:Y 2 O 3 ceramic laser materials. This far-from-equilibrium processing methodology allows higher levels of rare earth doping than can be achieved by equilibrium methods. The method comprises of two main steps: (a) plasma melting and quenching to generate dense, and homogeneous doped metastable powders, (b) pressure assisted consolidation of these powders by hot isostatic pressing to make dense nanocomposite ceramics. Using this process, several 1" x 1" ceramic cylinders have been produced. The infrared transmission of undoped Y 2 O 3 ceramics was as high as ~75% without anti-reflection coating. In the case of Nd:Y 2 O 3 ceramics infrared transmission values of ~50% were achieved. Furthermore, Nd:Y 2 O 3 samples with dopant concentrations of up to ~2 at. % were prepared without significant emission quenching.

“…In 2000 and 2001, Lu et al reported the operation of diode pump Nd:YAG ceramic lasers with ceramic samples made by Konoshima Chemical. The output power was gradually increased from 31 W to 110 W [8][9][10][11] . Extensive studies have shown that the thermal and mechanical properties of the ceramics are better than those of YAG single crystals [12,13] .…”
