One year ago, researchers at Nichia Chemical Industries in Japan announced the development of a continuously operating laser diode that produced light emission at blue wavelengths. In his Perspective, Fasol describes the latest research from Nichia, in which a new blue laser architecture has been developed that promises continuous operation for 10,000 hours. At this level of reliability, the blue laser begins to meet the needs of many commercial applications, such as full color displays, high-density data storage, and optical communications.
