Information × Registration Number 0208U000819, 0105U001134 , R & D reports Title Investigation of the influence of ultrasonic treatment of corundum melt on the structural and optical quality of sapphire and ticor crystals popup.stage_title Head Krivonosov Evgeniy Vladimirovich, Registration Date 20-02-2008 Organization Institute for Single Crystals National Academy of Sciences of Ukraine popup.description2 It is established that ultrasound can interact with bulbs in the bulk of the liquid. Ultrasound with a frequency of 400-450 kHz and (1-5).10(4) Pa amplitude of acoustic pressure diminishes the content of pores in the process of crystallization by 2-2.5 times, Further thermal treatment of the crystals in media with neutral and reduction chemical potential improves the main working characteristics of ticor laser elements (FOM-factor, laser strength and generation efficiency) by 20-30%. This allows to obtain laser elements with a diameter up to 30 mm.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
