ASU Researchers Demonstrate White Lasers that Could Potentially Replace LEDs

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. The researchers have created a novel nanosheet capable of lasing in any visible color, completely tunable from red, green to blue, or any color in between.
