Abstract
A spectroscopic study of the green (S-4(3/2)-->I-4(15/2)) and blue (P- 2(3/2)-->I-4(11/2)) emissions from Er3+:Ca3Al2Ge3O12, induced by a red tunable laser excitation is reported. The green emission is due to ei ther an excited-state energy transfer or an excited-state absorption, depending on whether the laser excitation wavelength is tuned on I-4(1 5/2)-->F-4(9/2) on I-4(13/2)-->F-4(5/2). The blue emission mainly resu lts from a three-step absorption process.
