Abstract

Despite the breathtaking progress of semiconductor diode laser technology in recent years there is still no such thing as a diode that emits blue light. A great deal of research effort is therefore being put into schemes for efficiently converting the near-infrared output from the best available diodes into green and blue coherent radiation. Recently Bill Kozlovsky and Bill Lenth of the IBM Almaden Research Center, California, USA, reported a result which represents the current high-water mark in this field. In collaboration with scientists at the IBM Zurich Research Laboratory they succeeded in generating 41 mW of blue laser light by using a nonlinear crystal to double the frequency of infrared radiation emitted by a GaAlAs diode laser.
