1500nm Erbium Laser

The emission wavelength is 1550nm laser, and the focal spot of 50μm is output by scanning mode. A certain amount of thermal stripping, appropriate thermal coagulation and obvious thermal effect are produced at the site of direct penetration of the coke spot, and the thermal effect produces the contraction of the collagen fiber. Thermal solidification and thermal stripping form a minimally invasive small hole with a diameter of 0.08-0.1mm and a depth of about 2mm.
