ABSTRACT:
The invention relates to a laser head comprising a laser diode and a connection device comprising a substrate card of dielectric material on which two disjoint conductive tracks are formed, the laser diode being mounted on said substrate and being electrically connected in series between the conductive tracks, the plate being disposed inside a metal box. Two connectors are mounted on the outside of the box, and each of them is connected to a respective one of said conductive tracks, a first connector serving to connect the laser head to an external electrical feed line, and a second connector being suitable for connection to an external load having a wide passband and an impedance selected so that the impedance of the laser head as seen from the inlet to the first connector is substantially equal to the impedance of the external electrical feed line.
