532nm green laser modules fiber coupled

Choice of fiber will depend on the specs of the laser (single vs multimode, power). Once you have the fiber, you would focus the laser beam down into the fiber core using a lens. Post the specs for your laser.

532 nm is green laser . It’s not easy being green. There are two type of the fiber: plastic and glass .

A green laser is unusual to be fiber coupled. The fiber coupled green laser is not for communication. If your module is not equipped with a connector fixture , you’ll have to improvise a precision mechanical coupling

Fiber coupling a laser is not that hard, especially for multimode (single mode is a little harder but not impossible). You can buy equipment to do it, but it does require a little bit of thought and effort.
