Abstract: A method and system are disclosed for curing polymeric materials including dental composites. Preferably, modulated light is used to control the formation of polymer chains in the polymeric material so that a cured polymeric material that has the desired physical characteristics for its intended function is formed. Formation of short chain and long chain polymers from monomers in the polymeric material is initiated and controlled by using a light source with a wavelength suitable for one or more initiators found in the polymeric material.

Abstract: A system and method are disclosed for providing a laser beam that is varied, such as being pulsed or modulated, rather than being a laser beam of constant intensity. Specific circuitry that includes timing and triggering means for pulsing a laser beam is disclosed, and methods and software for modulating a laser beam are disclosed. Pulsed and modulated laser beams have wide variety of applications, including curing polymeric materials such as dental composites. Modulated light from sources other than lasers may also be used for such curing.

Abstract: An inventive system integrating a laser head and power supply in a novel fashion is described. The integral laser head and power supply utilizes a power supply heat sink which circumferentially surrounds the laser head. Also incorporated is a circuit board so sized and configured to allow for placement of the laser head therein. High technology components are also preferably employed to allow minimization of size and weight. The resulting integral laser head and power supply enjoys a significant reduction, approximately half, in both size and weight.

Abstract: A laser that is capable of producing light from a chosen group of frequencies not adequate or available using a single gas laser is provided. The laser is capable of producing selected and well defined light wavelengths. The laser is also capable of eliminating unwanted frequencies in order to prevent such frequencies from competing with (robbing power from) the desired wavelengths. The laser constitutes a multiple gas laser. A combination of argon and krypton is used. Argon is known to produce a good blue laser beam in the area of 488 nm. Mixed with the argon is krypton. Krypton also produces a blue output at 482 nm and 476 nm. In addition, krypton produces strong outputs in red, yellow, and green wavelengths (647 nm, 568 nm, and 529 nm respectively). Accordingly, access to each of these colors is provided by the argon-krypton in the mixture. Certain light frequencies are unnecessary and undesirable. Elimination of undesirable wavelengths is accomplished primarily through the optics used.
