Growth and Spectra of YCOB and Nd:YCOB Crystals
نویسنده
چکیده
Yttrium calcium oxoborate (YCOB) and Nd:YCOB crystals of high optical quality and large dimension have been grown by the Czochralski method. Measurements of refractive indices have confirmed that these crystals were negative biaxial. The absorption spectra were determined and the various spectrum parameters were calculated. Polarized absorption spectra revealed the strong anisotropic character of Nd:YCOB . Raman spectra indicate that the nonlinearity of the crystal is mainly attributed to planar BO3 triangles in the structure rather than to a distortion of oxygen octahedra.

Growth of CsI(Tl) crystals doped with Ca and Tm and investigation of its scintillation characteristics
In this work, the growth of CsI(Tl) crystals as gamma detector was performed using vertical Bridgman method with Ca and Tm co-dopants. For evaluation of the growth crystals, X-Ray Diffraction (XRD), photoluminescence and thermoluminescence spectra as well as recorded gamma spectra were employed. In addition, the scintillation properties including energy resolution, scintillation decay time, abs...

Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...
متن کاملEnergy and average power scalable optical parametric chirped-pulse amplification in yttrium calcium oxyborate.
Optical parametric chirped-pulse amplification (OPCPA) in nonlinear crystals has the potential to produce extremes of peak and average power but is limited either in energy by crystal growth issues or in average power by crystal thermo-optic characteristics. Recently, large (7.5 cm diameter x 25 cm length) crystals of yttrium calcium oxyborate (YCOB) have been grown and utilized for high-averag...
