Next Big Future: First white laser paves way for better computer screens, televisions and laser wifi 1000 times faster than wifi

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.

Researchers at Arizona State University have solved the puzzle. They have proven that semiconductor lasers are capable of emitting over the full visible color spectrum, which is necessary to produce a white laser.
