Abstract: Provided is a laser dazing apparatus shaped as a pistol having an encasement formed by a elongated barrel (114) joined to a handle (117), together forming an encasement. The barrel (114) has a forward end and a rear end, and the handle (117) is connected to the barrel (114) towards the barrel's rear end. The barrel encasement (114) also includes an adapter ring (111) with a focusing fixture (112) for controlling divergence of radiation produced by the device. The apparatus also includes various indicators, a laser generator, a least one battery for electrical power, and a plurality of control circuits controlling the laser generation device, battery, indicators and switches. The apparatus also includes a focus range adjuster (105).

Abstract: A laser pumped tunable laser system is disclosed directed to achieving tunable outputs with high wall plug efficiencies. In particular, green laser pumped alexandrite lasers are discussed—both pulsed and CW—where the wall plug efficiencies of greater than 2% can be achieved using practical, commercially available pump lasers. In alternative approaches, frequency converted tunable radiation in the UV is achieved with high efficiency from compact, high beam quality devices.

Abstract: An anti-counterfeiting method and apparatus causes a first mark to be produced on an object such as a pill in a package and then causes a second mark to be produced on said object while also producing said second mark on the plastic package cover over said object. A first laser beam producing means produces a first laser beam, preferably in the IR spectrum, and produces said first mark on the object when the beam passes through said cover. A second laser beam producing means produces a second laser beam preferably in the UV spectrum. The second laser beam also passes through said cover and produces said second mark superimposed on said first mark on said object. The second mark is always different from said first mark. Continued passing of said second beam through said cover causes said cover cloud up and form said second mark on said cover also.
