He discovered the nonlinear optical crystals BBO, LBO and KBBF, which have important uses in areas including superconductor research, semiconductor photolithography, and the medical industry. The as-grown crystals were also characterized by microhardness measurement.

By localizing the nucleation process in a small, predetermined area, we are able to limit the number of nuclei, which significantly helps us to grow large single crystals and also improve crystal optical quality.

.css('font-weight', '600'); Chen Chuangtian (Chinese: 陈创天; 18 February 1937 – 31 October 2018), also known as Chuang-Tian Chen, was a Chinese materials scientist and physical chemist who specialized in crystals used in lasers. Macroscopic terraces are usually observed on the surface of as-grown KBBF crystal due to the lack of supply of solute (KBBF) in the later period of growth. KBBF single crystals up to 3.7 mm in thickness have been grown for the first time from KBF4 and KF–B2O3 solution systems. jQuery('.alert-link')

This Small Business Innovative Research Phase I project is to develop a commercial growth process for single crystals of KBe2BO3F2 (KBBF) using hydrothermal techniques. .css('display', 'flex') This crystal is often used for second harmonic generation (SHG, also known as frequency doubling), for example of Nd:YAG lasers (1064 nm → 532 nm). KBe 2 BO 3 F 2 (KBBF) is the only nonlinear optical (NLO) crystal that can produce deep-UV harmonic generation below 200 nm through a simple secondary harmonic (SHG) generation method .Since it is difficult to obtain a KBBF crystal thicker than 2 mm in high temperature flux system , , alternative crystal growth methods such as hydrothermal method (HM) have started to … .css('font-weight', '700') Updates.

KBBF is a nonlinear optical high purity YLF laser crystal material that converts laser light into an unprecedented 176 nm wavelength (deep ultraviolet) laser, enabling the fabrication of deep ultraviolet solid-state lasers.

.admin-menu.alert-message { padding-top:25px !important;} This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). As mentioned above, eight large bulk KBBF crystals with thickness above 4.4 mm along the c-axis can be obtained in one case through many improvements in the crystal growth technique.

The growth rate of KBBF crystals along [0 0 0 1] direction was 0.035–0.040 mm/day, lower than that in the conventional mineralizers, and the quality of the as-grown crystals was proved to be better by the X-ray rocking curve measurement.

The structure of the KBBF crystal is formed by weak linking of layers stacking, so the layered growth is the main characteristic, and (0 0 0 1) is the cleavage plane. KBBF (Potassium beryllium fluoroborate) is a non-linear crystal used in optical applications.
