Abstract—Transparent Tm,Ho:YAG ceramic with excellent optical properties was fabricated by solid-state
reaction method using high-purity commercial powders as raw materials. Optical absorption and 2.0 m emis-
sion spectra of the ceramic specimen have been studied. The strongest emission corresponds to ⁵I₇ ⁵I₈ tran-
sition of Ho³⁺ centered at 2.06 m. As a result, Tm,Ho:YAG ceramic shows potential application in 2.0 m laser
devices.
