Abstract : Disclosed is a capability for training and other uses wherein a firearm can be aligned with its target by use of a laser beam, or the target can be designated to others by illuminating it with the laser beam. A laser diode that provides visible light is used in conjunction with the boresight of a gun to paint a visible spot on an intended target at the location the bullet will impact if the weapon were fired, The beam emitted by the diode is collimated by a miniature gradient refractive index lens co-located with the diode on a heat sink that is included to convey heat away from the heat sensitive components. A circuit having a photodiode and a differencing amplifier is included to provide stability in the output of the laser, in order to overcome the effects of thermal excursions, and to protect the reflective surfaces of the laser from power surges. The on-off switch is a pressure sensitive material removably attached to the gun in a convenient location for it to be operated by the user's gun hand.
