The series of single-module CW lasers adopt unique optical structure design, and can achieve single-mode output through 20um optical cable. The energy density can reach up to 2.4 million watts per square millimeter, which is especially suitable for sheet metal cutting and application environments with higher energy density requirements. As a fiber laser developed with the latest technology, the electro-optic conversion efficiency is as high as 42%. Its simple design features, light weight, and rack-type fixing method can facilitate more compact equipment integration, reducing the number of transportation and disassembly and potential risk.
