laser crystal The active ions used in laser crystals are mainly transition metal ions and trivalent rare earth ions. The optical electrons of transition metal ions are 3d electrons located in the outer layer. In crystals, these optical electrons are susceptible to the direct effect of the surrounding crystal field. Therefore, their spectral characteristics vary greatly among crystals with different structure types. The 4f electron of trivalent rare earth ions is shielded by 5S and 5p outer electrons, which weakens the effect of crystal field. However, the perturbation of crystal field makes it possible for the forbidden 4f electron transition to produce narrow band absorption and fluorescence lines. So the spectra of trivalent rare earth ions in different crystals do not change as much as those of transition metal ions. The matrix crystals used in laser crystals are mainly oxides and fluorides. As a matrix crystal, besides its stable physical and chemical properties, it is easy to grow...

BBO nonlinear crystal As one of the most important nonlinear optical crystals, beta-barium borate (β-BaB2O4，β-BBO) combines many outstanding features such as its high nonlinear optical coefficients, low group-velocity dispersion, broad transparency range (189–3500 nm) and high damage threshold. This unique combination ensures β-BBO crystal a promising candidate for a wide range of nonlinear optical applications such as frequency converters and optical parametric oscillators. In the realm of quantum optics, β-BBO crystal can be used to generate entangled photon pairs and ten-photon entanglement. β-BBO Nonlinear Crystal—a widely used nonlinear crystal for frequency conversion in the ultraviolet, visible and near-infrared BBO is a negative uniaxial crystal, which provides phase matching for various second-order interactions almost over its entire transparency range (from 185 nm to 3.3 µm, as deduced from the transmittance measurements using crystal samples of several mm thickness), making...

Co:spinel Q-Switch crystal Cobalt-doped magnesium aluminate spinel (Co:MgAl 2 O 4 ) allow the generation of short nanosecond pulse with high peak power around the eye-safe wavelength of 1.5um,perfect for telemetry applications. The absorption spectrum of Co 2+ -doped MgAl 2 O 4  exhibited a broad absorption band in the wavelength range of 1200–1600 nm, which indicated that Co 2+  ions substituted for the tetrahedrally coordinated Mg 2+  ions in the MgAl 2 O 4  lattice. Passive Q-switching of solid-state lasers with solid-state saturable absorbers is a very attractive Q-switching technique because it allows to develop compact and low cost laser sources of nano and sub nanosecond pulses far various applications Co spinel——saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe wavelength of 1.5 μm Lasers emitting at 1.5µm are of great interest for several industrial applications. This interest is, first of all, due to eye-safety of 1....
