“…It is an efficient scintillator at low temperatures, and has gained a lot of interest due to the possibility of combining laser and Raman properties in the same media [9]. Both pure and rare earth doped SrWO 4 are used as Raman converters, amplifiers and lasers [10][11][12][13]. Some little work was reported by Patel and Arora [14,15] and Packter and Roy [16] on the crystal growth.…”

Single crystals of calcium tungstate and strontium tungstate have been grown by double decomposition flux reaction technique using lithium chloride as flux. Growth conditions are optimized to synthesize well faceted crystals. Effect of primary and secondary flux density in the growth charge has been studied. Thermogravimetric study reveals that the grown crystals are highly stable in the temperature range 25 -1000°C. Analysis of optical absorption normal to the ab-plane in the spectral range of 200 -800 nm reveals the true absorption edge, the nature of transition being the allowed indirect one at 4.60 eV and 4.56 eV respectively for CaWO 4 and SrWO 4 . The crystals have been characterized by determining useful pertinent optical and dielectric parameters.

“…It has a wide spectral transparency range from 0.255 μm to 3.7 μm. The steady-state Raman gain of BaWO 4 crystal was measured to be 8 cm/GW at 1064 nm and 36 cm/GW at 532 nm [13]. These gain values are one of the highest among the known solid-state Raman shifters.…”

Abstract:The output properties of an efficient extracavity BaWO4 Raman laser are investigated. An actively Q-switched Nd:YAG laser is used as the pumping source. The pulses have a pulse width of 11.7 ns and an energy up to 80 mJ. The Raman laser cavity is a flat-flat one. Four output couplers with different reflectivities for the first and second Stokes wavelengths are used in the experiment. The relations between the output pulse energy and the pumping pulse energy are measured. With an incident pulse energy of 66.2 mJ, the obtained maximum pulse energy of the first Stocks is 39.9 mJ, the corresponding conversion efficiency is 60.4%. When the pump pulse energy is 64.6 mJ, the obtained maximum pulse energy of the second Stocks is 22.8 mJ, the corresponding conversion efficiency is 35.3%. Dependence of the first Stokes pulse conversion efficiency on the incident pump pulse energy for different output couplers

Intense and broad visible photoluminescent (PL) band in structurally disordered SrWO4 compounds was observed at room temperature. The polycrystalline scheelite strontium tungstate (SrWO4) samples prepared by the polymeric precursor method at different temperatures of annealing were structurally characterized by x-ray diffraction and Fourier transform Raman spectroscopy measurements. Quantum-mechanical calculations showed that the local disorder in the cluster of the network modifiers Sr has a very important role in the charge transfer. The experimental and theoretical results are in good agreement, indicating that the generation of the intense visible PL band can be related to short-range order-disorder degree in the scheelite structure.
