Effect of disordered structure and crystal defects on heat transfer behavior in Er:Yb: YCa4O(BO3)3 crystal

Preparation and spectral analysis of 4.3%Dy:YCa4O(BO3)3 and 5%Dy,1.25%Tb:YCa4O(BO3)3 crystals for potential use in solid state yellow lasers

“…14 YCOB crystal is an excellent non-linear optical material, which has high phonon energy and high thermal conductivity and is not likely to deliquesce, etc. 15 The level spacing of Dy 3+ : 6 H 13/2 → 6 H 15/2 is about 3300 cm −1 . The high phonon energy is beneficial to improve the probability of the transition Dy 3+ : 6 H 13/2 → 6 H 15/2 .…”

Growth and characterization of a highly homogeneous Er0.12Y0.88COB crystal for nonlinear optical applications

“…Therefore, Er:YCOB and Er,Yb:YCOB crystals with low Er 3+ doping concentration have been studied for gain media (1.5-1.6 μm laser). [26][27][28] In this paper, we describe our effort to grow a highly homogeneous Er:YCOB crystal and explore the possibility of its application in QPCPA technology. Besides, crystalline quality, composition uniformity, specific heat and thermal conductivity of the as-grown Er:YCOB crystals are studied.…”

Nature and spatial distribution of extended defects in Czochralski-grown Ca3RE2(BO3)4(RE = Y, Gd) orthoborate single crystals

“…Single-crystal defect structure has been also analyzed for Ca 4 GdO(BO 3 ) 3 by transmission and back-reflection x-ray topography [36], optical conoscopy, and spectropolarimetry [37]. Another single crystal from the same family-Er and Yb co-doped Ca 4 YO(BO 3 ) 3 -has been characterized by means of x-ray synchrotron transmission topography [38,39] and chemical etching [39].…”
