Growth of nonlinear optical crystal CsB3O5 from self-flux solution

Growth of large CsB3O5 crystals

“…However, the growth of CBO crystals still encountered a serious problem regarding volatilization, which makes it difficult to grow large and excellent quality crystals. The effect of volatilization on the growth of CBO crystals has attracted many a researchers' attention [9][10][11]. In this paper, a 3-mol% Cs 2 Oenriched melt was employed due to its smaller evaporation.…”

Enhancement of the CsB3O5(CBO) crystal quality by fast cooling after crystal growth

“…The dried growth material was charged in a platinum crucible and heated in steps of various temperatures. The detail crystal growth process can be found in [3]. After growth, the crystals were pulled out of the solution and immediately cooled to 500 1C at a rate of 17, 55, 110, 330 1C/h, respectively, and then at 17 1C/h to room temperature [8].…”

“…Scattering centers were responsible for the optical loss and reduction in the third-harmonic efficiency [3,4]. In our previous study, we proposed the existence of retrograde solid solution region at high temperatures in CBO and the scattering centers may be the result of the imperfections during the cooling process [5].…”

Formation mechanism of scattering centers in BaMgF4 single crystals

“…To observe scattering centers in the as-grown crystals, the 10 mW second harmonic of a diode-pumped Nd 3 + -doped YVO 4 laser (532 nm) was taken instead of a He-Ne laser [15] because the red laser was not as effective to examine some lightly scattering BMF crystals. In order to examine the effect of heat treatment on the scattering centers, we first determined the crystal's melting point.…”
