ABSTRACT:
A laser diode unit, having advantages of dissipating heat quickly, being capable of protecting itself from being destroyed by an incidental electrostatic or electric voltage, being effective to deal with the operations of aligning, positioning, adjusting, and being easy to be mass-produced. The laser diode unit includes a laser diode element for emitting laser light beam; a mold housing for securing the laser diode element thereon, laser light beams emitting from the laser diode element being capable of penetrating the mold housing; a collimating lens set disposed within the mold housing for collimating the light of the laser beam emitting from the laser diode element; and an adjusting means for driving the collimating lens set to move to and fro within a through bore formed in the mold housing.
