BLUE-GREEN DIODE-LASERS

The development of compact, reliable and inexpensive short-wavelength lasers is certain to have profound effects on virtually any technology that uses coherent visible light. Although the impact of such devices will be far-reaching, the primary driving force behind efforts to develop blue-green diode lasers is without question optical recording. The demand for increased data storage capabilities is continually forcing the recording industry to increase storage densities. The road to the realization of short-wavelength, wide-bandgap, II-VI semiconductor diode lasers was fraught with scientific challenges. © 1994, American Institute of Physics. All rights reserved.
