Why Are Lasers Red? Diodes, Cost, and History
The color a laser diode emits depends on its bandgap, which is the energy gap that electrons must cross to release a photon. A smaller energy gap produces longer-wavelength (redder) light, and a larger
Nick Holonyak
OverviewEarly life and careerInventionsCommemorationFurther reading
Nick Holonyak Jr. was born on November 3, 1928, in Zeigler, Illinois, to Rusyn immigrants. His father worked in a coal mine. Holonyak was the first member of his family to receive any type of formal schooling. He once worked 30 straight hours on the Illinois Central Railroad before realizing that a life of hard labor was not what he wanted and he would prefer to go to school instead. According to a Chicago Tribune article in 2003, "The cheap and reliable semiconductor lasers critical to DVD players, bar cod
