ASU researchers demonstrate the world’s first white lasers

ASU researchers demonstrate the world?s first white lasers

More luminous and energy efficient than LEDs, white lasers look to be the future in lighting and light-based wireless communication. While lasers were invented in 1960 and are commonly used in many applications, one characteristic of the technology has proven unattainable. No one has been able to create a laser that beams white light.
