Laser diode connector assembly

A connector body 4 encircling an optical focusing element 5, a laser diode 3 having an emission axis aimed along an axis at an absorption end 6 of the focusing element 5, the focusing element 5 converting diverging optical emission of the laser diode 3 into a converging beam of radiation, and a coupler element 7 contacting the focusing element 5 without an air gap therebetween to receive the beam of radiation without backward reflection, the connector body 4 having a socket 9, and the coupler element 7 having a front end 8 in the socket 9 for physical contact with an end 10 of an optical fiber 2 disconnectably inserted in the socket 9.
