“…The absorption spectra of the samples show a strong absorption band in the 495 nm range for X, Y and Z, and an additional band in the Z direction located at 565 nm (Figure 5a, Table I). The absorption bands in the visible are assigned provisionally to Ti 3+ which replaces Al 3+ in the chrysoberyl structure, which is consistent with literature data (Segawa et al, 1987;Anzai et al, , 1988Sugimoto et al, 1989). The spectra from the randomly orientated faceted stones (Figure 5b) are consistent with these data.…”

The estimated densities of the H 2 S phase (0.58 to 0.77g/cm 3) in isolated and fracture-bound multiphase inclusions in tanzanite have been used to model equilibrate and the contents will be lost through leakage and/or decrepitation. The internal pressures beyond which 'typical' microscopic inclusions in zoisite will leak (P d) but for larger inclusions (>100 μm) this value will be much lower. Thermophysical 10 μm) inclusions in zoisite would not survive the heating process to temperatures but the largest (c. 100 μm) will decrepitate or leak at even lower temperatures. Alignment of planar groupings of re-equilibrated inclusions will produce zones of investigation (Taylor et al., 2013) that microscopic H 2 S inclusions (c. 20 to 100 μm) not been heat treated.

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)

“…The polarization of the IR optical field is parallel to the a axis of the crystal. The Ti:Ch amplifier with E∥b has a bigger absorption section than that with E∥a, at around 500 nm [17]. Therefore, the Ti:Ch media should be pumped with frequency doubled Nd:YAG lasers with E∥b.…”

“…With the light field polarization parallel to the a axis (E∥a), an emission peak could be observed at each side of 800 nm in the photoluminescence spectrum of Ti:Ch. The Ti:Ch gets maximum absorption at around 500 nm [17], which ensures that the second harmonics of Nd:YAG lasers are proper pumping sources for Ti:Ch amplifiers.…”
