Abstract

Polyerystalline material preparation and single crystal growth of Yb:YCa4O(BO3)3 (Yb:YCOB) have been studied. The 20% atom fraction Yb doped Yb:YCOB single crystal with high optical quality has been grown by the Czochralski method. The absorption spectra, fluorescence spectra and fluorescence lifetime of Yb:YCOB were measured. Laser operation of Yb:YCOB crystal pumped by diodes was demonstrated and 10 mW of 1032 nm laser output was obtained using 976 nm pump diodes. A self-frequency-doubling green light was also observed.
