Abstract
Room-temperature green upconversion fluorescence of an Er3+-doped POCl 3-SnCl4 solution is achieved when the solution is pumped with an 800-n m GaAs laser diode. The upconversion emission at 550 nm is determined to be the result of a two-step absorption process. Numerical analysis reveals that laser systems that employ this erbium-doped laser liquid should be realizable with threshold pump powers as low as 45 mW. (C) 1 996 Optical Society of America
