“…However, accumulated knowledge and experience in this field of investigations (see, e.g. [11,18,21,66,67]) can give us confidence that in the near future the results of this research will be more perceptible. This could also significantly help in investigating novel pumping technologies.…”

“…Stokes SRS can also improve the spatial quality of laser beams as well as the contrast between peak and background intensities of ultra-short laser pulses, etc. [14,15,66,103,[383][384][385]. The investigation of SRS in crystalline solids (it is likely that natural diamond and calcite were used) dates from 1963 [304].…”

After a brief examination of known insulating laser crystals and the stimulated emission channels of their generating activator ions, this article reviews recent advances in the development of novel lasing crystals and ceramics, as well as inorganic and organic nonlinear-laser crystals for χ (3) and cascaded χ (3) ↔ χ (2) frequency converters. Several new modern attractive technologies in the physics and techniques of crystalline lasers are also discussed.Section of the crystal structure of Na3Li (SeO4)

“…This result indicates the existence of fast exciton diffusion among Yb 3ϩ ions before starting the Yb→Er direct energy transfer. The K d transfer rate was calculated using the following expression well known for the donor to acceptor energy transfer assisted by excitation migration among donor ions ͑or diffusion model͒: 20 It is important to note that ␥͑exp͒ values are always higher than ␥͑theor͒ values and ␥ 2 (exp) is higher than K d . Also we observed that the measured lifetime of the Er 3ϩ ( 4 I 11/2 ) state in codoped samples is shorter ͑2.4 -5.4 ms͒ than the measured lifetime of the isolated Er 3ϩ ( 4 I 11/2 ) ion ͑ϳ7 ms͒.…”

The mechanism of the Yb 3ϩ →Er 3ϩ energy transfer as a function of the donor and the acceptor concentration was investigated in Yb 3ϩ -Er 3ϩ codoped fluorozirconate glass. The luminescence decay curves were measured and analyzed by monitoring the Er 3ϩ ( 4 I 11/2 ) fluorescence induced by the Yb 3ϩ ( 2 F 5/2 ) excitation. The energy transfer microparameters were determined and used to estimate the Yb-Er transfer rate of an energy transfer process assisted by excitation migration among donors state ͑diffusion model͒. The experimental transfer rates were determined from the best fitting of the acceptor luminescence decay obtained using a theoretical approach analog to that one used in the Inokuti-Hirayama model for the donor luminescence decay. The obtained values of transfer parameter gamma ͓␥͑exp͔͒ were always higher than that predicted by the Inokuti-Hirayama model. Also, the experimental transfer rate, ␥ 2 (exp), was observed to be higher than the transfer rate predicted by the migration model. Assuming a random distribution among excited donors at the initial time (tϭ0) and that a fast excitation migration, which occurs in a very short time (t Ӷ␥ Ϫ2 ), reducing the mean distance between donor ͑excited͒ and acceptor, all the observed results could be explained.
