Long-pulse Green Laser has high single pulse energy and high peak power, which is optimal for welding of such high-reflective materials as copper and gold. With the development of consumer electronics and new energy industries in recent years, the demand
At room temperature, the near infrared laser absorption of copper is less than 5%, while the green laser absorption can reach 40%. The output wavelength of PG3 is 532nm green laser, the output pulse peak power is 1KW, and the maximum single pulse energy is 3J. Compared with 1064nm near infrared laser, the output beam is better with shorter wavelength. In addition, the green light energy feedback system is adopted to improve the energy stability (≤3%) of the output laser.
