Avalanche upconversion in Er3+ doped fluoroindate glass
Avalanche upconversion is reported for Er3+ doped fluoroindate glass pumped at 633.5 nm. Strong frequency upconversion signals and intensity dependent transmittances are observed. The results of the transient and steady-state measurements agree well with the predictions of a rate-equation model whic...

| Zusammenfassung: | Avalanche upconversion is reported for Er3+ doped fluoroindate glass pumped at 633.5 nm. Strong frequency upconversion signals and intensity dependent transmittances are observed. The results of the transient and steady-state measurements agree well with the predictions of a rate-equation model which take into account cross-relaxation processes among pairs of erbium ions. |
