Abstract: A laser collimating module includes a heat dissipating base having a fixing element on a top thereof and a plurality of pins at a bottom thereof, a laser diode chip disposed on the fixing element, a cap covering on the heat dissipating base with a placing space therein and an opening on a top thereof, and a cylindrical lens disposed in the placing space. The opening of the cap is connecting to the placing space and aligning with the laser diode chip correspondingly. The cylindrical lens has a first surface facing toward the laser diode chip with a first minimized distance arranged therebetween and a second surface facing toward the opening with a second minimized distance arranged therebetween. The laser diode chip is stimulated and emits an elliptical laser beam, and a light emitting angle is formed. As the elliptical laser beam passes through the cylindrical lens, the light emitting angle is narrowed and the laser beam is collimated to be a linear beam.
