Yb:YAP Scintillator A Promising Laser Crystal for Diode-Pumped Solid-State Lasers Yb YAP Scintillation Crystal In recent years, Yb 3+-doped crystals have attracted a great deal of attention with the rapid development of diode pumped solid-state laser (DPSSL).  Yb:YAP  has demonstrated many attractive characteristics, such as longer lifetimes, higher polarized cross-sections, lower thermal load, very short fluorescence decays and high laser energy capacity. It is a very promising laser crystal in laser-diode-pumped solid-state configurations and neutrino detection. Because of the simple electronic structure of Yb 3+ion, which consists of only two levels, such unfavorable processes like excited state absorption, up-conversion or cross-relaxation are absent in Yb3+lasers.

Ce:BaF2 Scintillator Crystal — A reasonably fast and rugged scintillator Ce BaF2 Scintillator Crystal BaF2 has a decay time of less than 1 ns, which makes it unique among the high-Z scintillators and consequently very attractive for many applications where good timing is important. BaF2 has a low refractive index of about 1.478 at a wavelength of 500 nm and can be relatively easily matched with a proper polymeric matrix. Moreover, BaF2’s conversion of light for ionising radiation is quite linear with energy. However, the integrated intensity of the fast component is low and the emission spectrum of BaF2 contains an exciton band with undesirably long decay time. This problem can be solved by the introduction of an activator, which transforms the exciton emission into the faster activator luminescence. Trivalent cerium has been became a natural choice for the activator, because the Ce3+ ion has a fairly short decay time. Ce:BaF2 scintillator is a well-known, reasonably fast an

Ce:LuAG Scintillator  Crystal — A  scintillation material suitable for high-power laser lighting Cerium-activated LuAG was proposed as a proper candidate scintillator and a potential phosphor to make white light-emitting diodes. Single crystal Ce:LuAG has better detection rate than isostructural cerium-activated yttrium aluminum garnet (Ce:YAG) because of its higher density and higher effective atomic number. Ce:LuAG was significantly better than the other phosphors with respect to the thermal quenching. In addition, the luminescence spectrum of Ce:LuAG contains a large enough green component. Ce:LuAG single crystals are also widely used as scintillation detectors for γ-rays and high energy particles. The latest generation Ce:LuAG crystal shows a high light yield up to 26,000 pH/MeV, which has been considered as potential candidate in PET scanners due to the six times shorter decay time and almost identical density. Besides, Ce:LuAG has excellent physical and chemical perform
