It is reported that the Korean research team has developed a "new generation of cyan laser light source" that is superior in performance to LEDs (light-emitting diodes).
South Korea's POSTECH (formerly Pohang University of Technology), the five professors of the Department of Electrical and Electronic Engineering, announced that it has pioneered the development of a "laser source" that outperforms LEDs.
The laser light source is a cyan laser light source that consumes less power and has a faster light-emitting speed when a semiconductor similar to the LED is used. In general, an LED is a semiconductor component that emits light when it is connected to an electric current. The efficiency is 10 times higher than that of an incandescent lamp, and the life is semi-permanent.
The cyan laser source developed by the Group of Professors of the Five Powers uses the same semiconductor material as the LED, but it differs in the point of emitting a linear light-laser. Quanta explained: "With the fine mirror structure of the ring shape made on the surface of the semiconductor, the laser is spirally radiated, so that the light can be diffused into the three-dimensional space. When the current is applied, the speed of the light is higher than that of the LED. It is hundreds or even thousands of times faster and consumes far less power than LEDs.
However, its actual efficiency and future development remain to be seen.
