Abstract

Step-wise two-photon excitation studies are useful for the development of upconversion lasers and infrared quantum counter devices. Our recent experimental results on erbium doped materials revealed efficient violet upconversion emission under diode laser excitation. Latest experiments on infrared quantum counter studies are also discussed. Different energy upconversion phenomena and the upconversion laser development are also reviewed in detail. A discussion is given on the estimation of excited state absorption cross sections.
