ABSTRACT:
The principle and some applications of multiphoton pumped upconverted lasers (MU-LASER) in complex molecules like said material is demonstrated. Weak linear absorption and strong multiphoton absorption and upconverted fluorescence of said material in the form of integrated waveguides is responsible for the MU-LASER action of upconverting narrow band infrared wavelength to visible spectrum of bandwidth.about.50 nm and peak at 570 nm. Applications in efficient upconversion of diode laser wavelengths, displays, and two types of surface-emitting MU-LASERs for high definition television (HDTV) are produced.
