Abstract:
1. A semiconductor laser module for emitting light, said laser module having a co-axial type package, comprising: a semiconductor laser diode having one electrode and another electrode for emitting said light by supplying a driving signal between said one electrode and said other electrode; a sub-mount for mounting said laser thereon, said sub-mount providing a first transmission line connected to said one electrode of said semiconductor laser diode and a second transmission line connected to said other electrode of said semiconductor laser diode; a stem including a disk-shaped base and a block disposed on said base, said block mounting said sub-mount thereon; and a first lead pin and a second lead pin provided in said base for inputting an first signal and a second signal, respectively, said driving signal being one of said first signal and said second signal, wherein said first lead pin and said second lead pin are directly connected to said first transmission line and said second transmission line, respectively.
