Improvement of EV/LIB by Visible and Invisible Hybrid Laser and CN Contribution

Abstract

EV/LIB, which is noted for the CN contribution, has been growing steadily year after year due to corona trouble. I visited the Shenzhen headquarters of China UW, which has Occupancy of China NO.1 as a laser for EV/LIB. This paper reports the current status and future development of the CN contribution by the EV/LIB laser in China, the visible hybrid laser represented by the blue laser, and the invisible hybrid laser by near Red LD and fiber laser. In the UW, we have succeeded in commercializing a blue DDL hybrid laser equipped with a super compact 500W blue laser in the head for the first time in the world, and we report its workability and future possibility.
