'ok' here's one for you can you transmit laser energy through a fiber optic cable? If you have a laser that melts metal, can you channel this type of thing through a fiber optic cable and still melt the metal? Or is there any other way to channel this type of laser? mirrors or something else? thanks -- http://www.piclist.com hint: The PICList is archived three different ways.
