Growth of KTP crystals with high damage threshold by hydrothermal method

Growth and optical properties of bulk KTP crystals by hydrothermal method

“…The growth process of hydrothermal KTP single crystals was described in the previous paper [10], using an improved solution of 2.0 mol/l K 2 HPO 4 +0.1 mol/l KH 2 PO 4 +1 wt% H 2 O 2 as mineralizer. Spontaneous KTP crystals grown from K 6 P 4 O 13 flux in closed Pt crucibles were used as nutrients.…”

“…The techniques presently carried out to grow KTP crystals are the flux method [1][2][3][4][5] and the hydrothermal method [6][7][8][9][10]. KTP crystals grown from flux are often poisoned by impurities (impurities such as Fe and other transition metals are very harmful to KTP [11][12][13]) during the growth process so that they usually possess a lower damage threshold and lower ability to anti-gray track.…”

“…In a previous paper [10], we have reported our growth of KTP crystals with high damage thresholds by the hydrothermal method. In this paper, we continue to report our growth progress and the study of optical properties of the hydrothermally grown KTP crystals.…”

Analysis of crystalline perfection of pure and Mo-doped KTP crystals on different growth planes by high-resolution X-ray diffraction

“…Generally two main techniques, namely hydrothermal and flux techniques, are used for the growth of KTP crystals (Zhang et al, 2006;Roth & Tseitlin, 2010;Wang et al, 2009). The hydrothermal process requires high temperatures (of the order of 773 K) and pressure (of the order of 1360 bar; 1 bar = 100 000 Pa) and the growth rate of KTP crystals is very low (Bierlein & Vanherzeele, 1989;Laudise et al, 1986).…”

Growth and properties of KTP crystals from a new flux

“…In order to obtain more applicable large single crystals, two main growth methods are commonly used, namely, the hydrothermal method [6][7][8][9][10] and the flux method [11][12][13][14][15]. The latter method is currently the most popular growth process for effecting large KTP single crystals with high optical quality.…”
