Oriented Reduced-Pressure Melts Growth Of The Vacuum Ultraviolet Double Frequency Crystal Kbe2bo3f2
A bulk vacuum ultraviolet double frequency crystal KBe2BO3F2 (KBBF) crystal has been grown successfully by using a method of oriented reduced-pressure melts growth,and the optical properties of the grown crystal,such as optical transparency and the second harmonic efficiency,were also measured.The results show that the high-frequency absorption edge is observed at 150nm and the optical transparency was up to 75% in the spectral range between 250nm and 400nm.The second harmonic efficiency was measured with an outer cavity frequency-doubling method and its maximal value was about 68.5%.The experimental researches indicate that the oriented reduced-pressure melts growth is a promising growth method for bulk KBBF crystal and it is possible for applying as a frequency-doubling device for the vacuum ultraviolet region.
