VIEW PDF: CONCENTRATION AND PUMP INTENSITY EFFECTS IN THE EMISSION OF Nd LASER MATERIALS
High doping concentrations useful for granting efficient absorption of the pump radiation can be hampered by the concentration-dependent self-quenching of emission due to energy transfer inside the system of doping ions. The paper discusses the pump intensity-dependent balance between the down- and upconversion processes in the Nd laser materials, based on their effect on emission dynamics. Reduction of emission quantum efficiency by self-quenching and its influence on the laser emission and heat generation is analysed.
Keywords: Nd lasers, energy transfer, down-conversion, upconversion, heat generation
