CW diode-pumped laser operation of Nd3+ in Ca3Sc2Ge3O12 (CaSGG) single garnet crystal has been demonstrated for the fil st time. We measured an 18% slope efficiency and 2.7-nm tunability with two different laser cavities. A spectroscopic characterization of our sample has also been performed including the absorption cross section in the 800-nm region and the emission cross section and radiative lifetime of the upper laser level.

Abstract
CW diode-pumped laser operation of Nd3+ in Ca3Sc2Ge3O12 (CaSGG) single garnet crystal has been demonstrated for the fil st time. We measured an 18% slope efficiency and 2.7-nm tunability with two different laser cavities. A spectroscopic characterization of our sample has also been performed including the absorption cross section in the 800-nm region and the emission cross section and radiative lifetime of the upper laser level.File in questo prodotto:
