In this paper, Er:Ca4YO(BO3)(3) (Er:YCOB) and Er:Yb:Ca-4 YO(BO3)(3) (Er:Yb:
YCOB) crystals with large size and excellent quality have been grown by the
Czochralski method. The absorption and emission spectra of Er:YCOB and Er:
Yb:YCOB crystals have been measured; the emission spectrum of Er:Yb:YCOB cr
ystal shows that the strongest emission peak is located at 1537 nm. An outp
ut power of about 2 mW at the wavelength of 1553 nm has been obtained under
the pumping power of a fiber-coupled laser diode (LD) of 1600 mW at 976 nm
, using a Y direction cut 2.5 mm thick Er:Yb:YCOB crystal sample. (C) 2000
