Physics basis of one-beam pumping upconversion three-dimensional volumetric display based on erbium-doped glass

Three-dimensional (3-d) volumetric display is urgently needed in the fields of air-transportation management, computer-assistant design, imaging application, biophysics, and congratulatory or entertaining art. Recently the growing i#information highwayi# has been accelerating the requirement for 3-d displays to show fast and complex pictures. Frequency up-conversion 3-d volumetric display, abstracting especially in its self-spatial vision, has the advantages of total-solidification, high reliability and speedy operation so that it has a broad range of application. Two-frequency up-conversion 3-d volumetric display was evaluated as the latest achievement of 1996 in physics. This paper careful investigates the one-beam pumping upconversion 3-d volumetric display , which is based on erbium Er doped glass. The bright-light facula length of one-beam pumping upconversion luminescence is studied by diode LD laser. The upconversion luminescence spectrum of Er doped glass is measured also. The physics basis of one-beam pumping upconversion 3-d volumetric display based on Er doped glass is discussed. This interesting result illustrates that the property of one-beam pumping 3-d volumetric display could be improved so much to achieve practical application greatly. As our best knowledge, similar result has not been reported.
