| In the Year of Professor Jan Czochralski, we with pleasure review the representative recent works of our group, Optical Single Crystals Group, NIMS, Japan. Our group has been working on the development of novel single crystals for optical applications based on the Czochralski technique. Here, 4 kinds of topics are reviewed. 1st one is ferroelectric fluoride BaMgF4 single crystals for UV nonlinear optical applications including quasi-phase matching device fabrications. 2nd one is transparent conductive β-Ga2O3 single crystals as semiconductor, which has large band-gap, 4.8 eV, for LED applications. 3rd one is F-doped core-free Y3Al5O12 single crystals as a potential new lens material for UV/VUV wavelength region. Last one is superior magneto-optical {Tb3}[Sc2-xLux](Al3)O12 single crystals for near infrared to visible region, and CeF3/PrF3 single crystals for UV region. |
