AbstractPump-excited-state-absorption (ESA) measurements on Er3+-doped phosphates, fluorophosphates, and silicate bulk glasses indicate that ESA cross sections are approximately equal to ground state absorption (GSA) cross sections in the 800-nm band. The oscillator strengths of the ESA and GSA bands are also approximately equal, in qualitative agreement with Judd-Ofelt calculations. Fluorozirconate samples were found to have substantial populations in the upper excited states for the measurement conditions used and ESA transitions originating from four excited states were identified. Fluorozirconate fiber amplifiers and lasers at 1.55 μm, therefore, would have decreased efficiency for 800-nm pumping.

Nonlinear optical response and reverse saturable absorption behavior of various rare earth phthalocyanines such as Nd , Eu , Sm and La in dimethyl formamide (DMF) solution were studied under high power Nd:YAG laser excitation. Excited state absorption cross-sections and two-photon absorption cross-sections of these systems are measured from the limiting characteristics. The SmHPc 2 system yields maximum value for excited state absorption cross-section and its potential application in DMF as a suitable optical limiter is also discussed.
