Blue/green Lasers Based On II-VI Semiconductor Heterostructures

Summary form only given, as follows. In June, 1991, scientists at 3M Company announced a blue/green laser diode based on wide-band-gap Il-VI semiconductor materials. Blue/green lasers have now been reported by at least nine research groups throughout the world, including NCSU. Work in this exciting new field will be reviewed, and recent NCSU results will be presented. Issues that must be addressed before these new short-wavelength light emitters can be commercialized will be described and possible solutions to these issues will be discussed. The potential market for blue/green/red/light emitters is expected to exceed $58 per year within five years.
