• Resumen

  • The article discusses the development of solid-state lasers able to produce green light. The ability of semiconductors to generate laser light only in the red and blue parts of the spectrum as of early 2009 is mentioned, noting that new techniques for growing laser diodes could result in the development of laser-based video displays due to the addition of light from the green portion of the spectrum.
