Claim:
1. A surface mount device type laser module, comprising: a housing having an opening; a base accommodated within the housing and comprising at least one surface transmission structure, wherein the at least one surface transmission structure is a contact pad which is exposed outside the base and the housing, and at least one electronic signal is transmitted through the at least one surface transmission structure; an edge-emitting type laser diode unit fixed on the base and providing at least one laser beam; and a reflective optical component; a photodiode unit disposed on or outside the base, wherein the edge-emitting type laser diode unit is arranged between the reflective optical component and the photodiode unit; wherein a first portion of the at least one laser beam is projected on the reflective optical component and then is reflected through the opening of the housing by the reflective optical component, and a second portion of the at least one laser beam is projected on the photodiode unit so as to be detected by the photodiode unit.
