Abstract

The blue—green lasers have great application in optical disk technology, image processing, color projection, printing and underwater optical communication. A good scheme for diode pumped frequecy doubling laser is diode pumpedself doublinglaser. In this kind of lasers, a single block of a compound—functionmaterial material was used both as the laser material to generate the fundmental laser and as the frequency doubling material to double the fundmental laser to the second harmonic, light. This kind of lasers have the advantages of compactness, high doubling efficiency, narrow breadth of spectrum line of second harmonic light, lower costs, and easy to adjust^[1,2,3,4].
