Title

Spectroscopy Of Yb,Ho Codoped Kyf4 And Its Application As Upconversion Green Laser

Abstract

Detailed room temperature absorption and emission spectra and the dynamics of the upconversion energy transfer were investigated in Yb, Ho codoped KYF4. It was found, in the concentration range studied, that the energy transfer rate from Yb3+ to Ho3+ ions is linearly dependent on Ho3+ concentration. The back transfer from Ho3+ to Yb3+ ions was demonstrated and the transfer rate was found to be superlinearly dependent on Yb3+ concentration. Discussions are presented on the optimization of Yb3+ and Ho3+ concentrations for the potential use of Yb, Ho codoped KYF4 as an upconversion green laser.
