Abstract: A system for detecting controlled substances on an object including at least one laser for illuminating at least part of an object with laser energy and either a second harmonic detector or a luminescence controlled substance detector, or both. Additionally, a system also including a Raman scattering controlled substance detector is disclosed.

Abstract: A laser system for treating features on the skin of a patient with laser light comprising: an imaging subsystem that locates features on the skin to be treated; a laser; laser optics that focuses light from the laser onto a feature located by the imaging subsystem; and a controller that when a feature is located, controls the laser to radiate a pulse of laser light that is focused by the laser optics to a spot localized about the feature.

Abstract: An alignment device for aligning a beam of radiant energy, particularly a laser beam, with respect to a target comprises a reflector in the path of the beam, the reflector having an aperture of a diameter smaller than that of the beam so that the aperture permits the center portion of the beam to pass therethrough to the target, while the outer marginal fringe of the beam is intercepted and reflected to a sighting member, the device further including an optical system transposing the image of the sighting member onto the field of the target, thereby enabling real-time alignment of the beam and providing a better defined beam and while permitting the alignment to be effected before directing the beam to the target.
