Epub 2013 Jun 19.Intense 2.0μm emission has been obtained in Ho(3+)/Tm(3+) codoped ZBLAY glass pumped by common laser diode. Three intensity parameters and radiative properties have been determined from the absorption spectrum based on the Judd-Ofelt theory. The 2μm emission characteristics and the energy transfer mechanism upon excitation of a conventional 800nm laser diode are investigated. Efficient Tm(3+) to Ho(3+) energy transfer processes have been observed in present glass and investigated using steady-state and time-resolved optical spectroscopy measurement. Read More
