Gongda Laser has launched a high-power continuousgreen laser to solve problems such as severe splashingduring welding of high reflectivity materials in the infra-red band, using a scheme of all fiber fundamental fre-quency and external cavity doubling. With an outputpower of up to 3000W, it is currently the highest powercontinuous green laser source in China. It has advantag-es such as high repeatability, high absorption rate, lesssplashing, high stability, and high beam quality.
