Abstract
One-color two-photon excitation spectra of the 4f(1) --> 5d(1) transit ions of Ce3+ in LiYF4 have been investigated at 5 K from 33 400 to 44 000 cm(-1). A sharp lorentzian line peaking at 33 439.4 cm(-1) with a width of 2.6 cm(-1) is observed on the low energy side of a band exten ding up to 35 200 cm(-1). The line and the band are observed to exhibi t different polarization dependences. A second band with a maximum pea king around 41 977 cm(-1) is observed to extend from 40 000 up to 44 0 00 cm(-1). No sharp line associated to this band is seen.
