20110122905 | SEMICONDUCTOR LASER ASSEMBLY AND PACKAGING SYSTEM - A system for self-aligning assembly and packaging of semiconductor lasers allows reduction of time, cost and testing expenses for high power density systems. A laser package mounting system, such as a modified TO-can (transistor outline can), has modifications that increase heat transfer from the active laser to a heat exchanger or other heat sink. A prefabricated heat exchanger assembly mounts both a laser package and one or more lenses. Direct mounting of a fan assembly to the package further minimizes assembly steps. Components may be physically and optically aligned during assembly by clocking and other indexing means, so that the entire system is self-aligned and focused by the assembly process without requiring post-assembly adjustment. This system can lower costs and thereby enable the use of high powered semiconductor lasers in low cost, high volume production, such as consumer items. | 05-26-2011 |
20110040358 | Portable Semiconductor Diode Laser for Medical Treatment - Semiconductor lasers, in which the laser diode output is used directly for medical treatment, can be compact, lightweight and efficient. Lasers operating in the relatively “eye-safe” window of about 1350-1600 nm can be used to treat wounds and diseases of the skin and other organs, for example to cut, ablate or coagulate bodily tissues and fluids. Because the wavelength is eye-safe, the treatment can be through-space, and does not require the use of a fiber optic containment system. The device need not directly contact tissue. Such devices can be battery operated, are portable and self-contained, and thus are suitable for uses that are not confined to medical facilities, including use in emergency situations and in military operations. | 02-17-2011 |
