| 摘 要： | 1 INTRODUCTION With the development of high power InGaAs laser diode (LD) as pump sources, the Yb3+-doped laser crystals have received much attention. Due to the simple energy level structure of the Yb3+ ions, the Yb3+-doped laser crystals have no concentration quenching, and have high quantum efficiency and low quantum defects even at high doping concentration of the Yb3+ ions1, 2]. Therefore, the Yb3+-doped crystals are good candidates of media in the LD-pumped solid-state laser,…

| Abstract: | The compound YbAl3(BO3)4 belongs to huntite, space group R32 with cell parameters: a = 9.251(2), c = 7.189(3) ? Z = 3, Dc = 4.574 g/cm3, F(000) = 675.0, V = 532.84 3, ?= 13.63 mm-1, (MoK? = 0.71073 ? Mr = 489.22, (YbAl3B4O12), the final R = 0.0286 and wR = 0.0710. The Yb3+ ion occupies the trigonal prismatic site and the Al3+ ion occupies the octahedral site. There are two sets of (BO3)3- planar triangles. The Yb3+ ions are connected by means of YbOAlB(2)]Yb with the distance 5.854 ? |
