Abstract

Appreciable excited-state absorption (ESA) in U²⁺:CaF₂ and Co²⁺:ZnSe saturable absorbers was measured at λ = 1.573 μm by optical transmission versus light fluence curves of 30-40 ns long pulses. The ground- and excited-state absorption cross-sections obtained were (9.15±0.3)×10^-20 and (3.6±0.2)×10^-20 cm², respectively, for U²⁺:CaF₂, and (57±4)×10^-20 and (12.5±1)×10^-20 cm² for Co²⁺:ZnSe. Thus, ESA is not negligible in U²⁺:CaF₂ and Co²⁺:ZnSe, as previously estimated.
