PEABODY, Mass., May 7, 2010 — SemiNex Corp. announces the Laser Engine, an integrated laser diode system designed for use by manufacturers of high-volume medical and other low-cost handheld applications. Based on proprietary and patented laser diode manufacturing technology, the system includes a high-efficiency laser, a heat spreader, a convection cooling device and an optical lensing element. It is available in 1470-, 1532- and 1550-nm wavelengths and features power conversion efficiency of 45% W/A, offering 3 W of continuous optical power from 6.5 A of input current. A version with greater power output is under development. The Laser Engine is suitable for medical applications such as acne removal, skin wrinkle reduction and skin ablation, and it also can be used in a range of professional applications like medical procedures and surgery, free-space communications and rangefinding. The system is available in two package options. The first integrates convection cooling and is 40 mm long with a diameter of 25 mm and a weight of 16 g, about the size and weight of a golf ball. The second is a conductively cooled package measuring 11 × 20 × 13 mm. In addition to the standard configurations, the company also can provide customers with a complete handheld laser system built on the Laser Engine that includes an integrated microprocessor control and battery power supply.
