Stimulated Raman Scattering in YVO4 and GdVO4 Crystals and Self Raman Frequency Conversion in Diode Pumped Nd3+:GdVO4 Laser

Presence of excited electronic state in CaWO4 crystals provoked by a tetrahedral distortion: An experimental and theoretical investigation

“…They continue attracting considerable attention because they are found to be fascinating systems possessing various technological applications, mainly including: microwave, scintillation, optical modulation, magnetic and writing-reading-creasing devices, humidity sensors, optical fibers, photoluminescence materials, 2,3 and promising nonlinear media for the transformation of the radiation wavelength in lasers, 4,5 or often, a combination of them. In addition, they have been extensively investigated as a self-activating phosphor emitting blue or green light under ultraviolet or x-ray excitation, 6,7 and they are good laser host materials.…”

Pure near-infrared to near-infrared upconversion of multifunctional Tm3+ and Yb3+ co-doped NaGd(WO4)2 nanoparticles

“…For YVO 4 :Tm 3+ ,Yb 3+ , Hazra et al 51 reported that the intensity of the blue upconversion peak was nearly as strong as that of the NIR emission. The Raman spectrum in Basiev's work 52 indicated that the phonons at $820 cm À1 participate in the PAET3 process, in which only two phonons are needed to ll up the mismatch, which is benecial for achieving the visible emission. This result also supports the PAET upconversion mechanism in our work.…”
