The invention relates to an optical fiber and a fiber termination which provide an output of laser light propagating through the fiber in a required direction while focusing it into a small spot. In one embodiment of the invention the termination includes a tapered fiber rod with an angled ball formed at the end of the rod. A corresponding method of manufacturing of the termination is provided. In another embodiment the termination includes a fiber rod having an angled end and a GRIN lens disposed so as to receive light reflected from the angled end, the lens being an integral part of the termination.
