It’s 520nm 4W fiber coupled laser module. The output fiber consists of 5 105μm fibers. The laser does not contain a drive circuit, and the drive circuit is external. The fiber beam combining module is a multi-tube core combined beam semiconductor laser. Large contact area, low current package form, more stable performance, more convenient to use. The optical fiber parameters can be customized, and the built-in cooling chip will make the device performance more reliable and stable. Let’s check it now.
