A surface mount device type laser module includes a housing, an edge-emitting type laser diode unit, a reflective optical component and a base. The base is accommodated within the housing, and the edge-emitting type laser diode unit is integrated into the base. The base includes at least one surface transmission structure. The at least one surface transmission structure is exposed outside the base and the housing. An electronic signal is transmitted through the at least one surface transmission structure. A laser beam provided by the edge-emitting type laser diode unit is reflected by the reflective optical component, and the reflected laser beam is transmitted through an opening of the housing.
