Lasers are an integral part of many modern applications, from laser pointers to optical communication networks. But current lasers are limited in their intensity, with most operating at powers of less than 100 watts. In a new breakthrough, researchers have developed lasers that are 10 times brighter than current lasers, paving the way for a host of new chip-scale applications.

The new laser is based on a gallium nitride (GaN) semiconductor, which is commonly used in LEDs and other optoelectronic devices. The researchers used a technique called “doping” to increase the efficiency of the laser and improve its power output. The result is a laser that emits light with an intensity 10 times higher than current lasers. This opens the door for a range of new chip-scale applications, such as optical sensing, communication, and medical imaging.

This breakthrough in laser technology could revolutionize the way we use lasers in everyday applications. With lasers that are 10 times brighter than current lasers, we can now explore a range of new chip-scale applications that were not possible before. From optical sensing to medical imaging, brighter lasers could open up a world of possibilities.
