Under 805-nm diode-laser excitation we detected intense upconversion signals at 410, 380, and 275 nm in BaF2:Er3+. Energy upconversion schemes and efficiencies are discussed in detail. Intensity parameters of Er3+ in BaF2 were derived as Ω2 = 1.048 ∓ 0.117 × 10−20 cm2, Ω4 = 1.478 ∓ 0.180 × 10−20 cm2, and Ω6 = 1.009 ∓ 0.127 × 10−20 cm2.
