Abstract
A surface mount device type laser module includes a housing, a vertical-cavity surface-emitting laser diode, a diffractive optical element and a base. The base is accommodated within the housing, and the vertical-cavity surface-emitting laser diode 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. Since the laser module is equipped with the diffractive optical element, the laser diffraction projection efficacy is achieved.
