FIG. 1.

Absorption spectra of as-grown and VTE-treated -cut MgO-codoped crystals in the wavelength range of . The insets show expanded views of three main absorption bands near 380, 520, and .

Image of FIG. 2.
FIG. 2.

Absorption spectra of the same as-grown and VTE-treated crystals as those of Fig. 1 in the infrared region of .

Image of FIG. 3.
FIG. 3.

(a) Absorption spectra of the same as-grown and VTE-treated crystals as those of Fig. 1 in the infrared region of . The inset shows an expanded view of the typical absorption peak near . (b) Infrared-absorption spectra of thermally calcined powder and singly Er-doped with procedures.

Image of FIG. 4.
FIG. 4.

Absorption band area of the manifolds , , , , , , and of in as-grown and VTE-treated -cut crystals. The values of the absorption band areas are also given explicitly as a data table. The solid line is only to guide the eyes.

Image of FIG. 5.
FIG. 5.

X-ray powder diffraction patterns of (a) -cut with the procedures and (b) -cut with the same VTE procedures. The value is indicated for each diffraction peak in unit of angstrom. The weak and broad diffraction peaks around the angle 30° or 59° as indicated in upper pattern are the characteristic diffractions with respect to the phase.

Image of FIG. 6.
FIG. 6.

absorption spectra of as-grown and VTE-treated -cut MgO-codoped crystals. The inset shows the decomposition of the absorption band of the as-grown crystal by using Lorentz two-peak fitting.

Image of FIG. 7.
FIG. 7.

Judd–Ofelt parameters ( , 4, and 6) of in as-grown and VTE-treated -cut crystals. For convenience, the values of are also given explicitly as a data table. The solid line is only to guide the eyes.

Image of FIG. 8.
FIG. 8.

Calculated radiative lifetimes of the manifolds , , , , , , , and of in as-grown and VTE-treated -cut crystals. For convenience, the values of the lifetimes are also given explicitly as a data table. The solid line is only to guide the eyes.
