ABSTRACT:
A self-contained laser module assembly has a diode laser and driver circuit enclosed with a cylindrical metal housing which forms a first electrical contact for inputting a DC voltage to power the circuit and laser. The housing has a first end which includes a lens positioned to emit a collimated laser beam along an axis of the housing and a second end including a second external electrical contact positioned to contact the power supply. One application of the module is in a pen-like pointer. The pointer includes conductive cap and body portions which are threaded together to house a laser module and a battery in end-to-end relationship. An O-ring between the battery and the body or module is axially compressed by tightening the cap on the body to enable turning on the pointer. The cap has a pocket clip through which electrical contact is selectably made between the body and a side contact on the module to cause a beam to be emitted.
