The first working laser was demonstrated in May 1960 by Theodore Maiman at Hughes Research Laboratories. Recently, lasers have become a multi-billion dollar industry. The most widespread use of lasers is in optical storage devices such as compact disc and DVD players, in which the laser (a few millimeters in size) scans the surface of the disc. Other common applications of lasers are bar code readers and laser pointers. In industry, lasers are used for cutting steel and other metals and for inscribing patterns (such as the letters on computer keyboards). Lasers are ... commonly used in various fields in science, especially spectroscopy, typically because of their well-defined wavelength or short pulse duration in the case of pulsed lasers.

This tunable BrightStar(TM) Alexandrite laser offers a more cost-effective solution than other laser technologies which are not wavelength tunable, like this new BrightStar(TM) Alexandrite laser. As a result, this new laser can serve more applications found in many areas of industry, government or the field of medicine. In one application such as remote sensing, this technology can better discriminate between various chemical and biological warfare agents (WMD's) scanning compounds at different wavelengths. The BrightStar(TM) Alexandrite laser emits a longer pulse, which provides a more stable non destructive light source which does not break chemical bonds as it finger prints a chemical or biological species. The UV light this laser emits can be transmitted into applications requiring beam transport through a fiber optic to a substrate or target. "We're using a highly reliable DP Nd:YAG green laser to pump the laser rod, which is the key to this technology.

"When we founded Aesthera Corporation our goal was to develop an innovative new procedure that would overcome the shortcomings of existing laser and light based technologies and be the treatment of choice for patients and practitioners alike," continues Anderson. "Photopneumatic Therapy achieves just that. During a PPx treatment, a handpiece is gently placed on the skin. In a fraction of a second, a vacuum gently draws the skin into the treatment tip bringing the targets such as hair follicles closer to the skin's surface. A painless light is applied which sends highly efficient photons to the target at 4-5 times the standard rate. Because the hair follicles are closer to the light, a lower energy can be used, providing an overall safer, painless procedure that's extremely fast and effective," concludes Anderson.

Laser Energetics believes its BrightStar(TM) Alexandrite laser technology, in its various forms, has many applications on the battlefield as well as for homeland security, including detection of chemical and biological warfare agents and detection of high explosives. The potential for future sales, given the size of the market, may well be in the hundreds of millions of dollars.

IntraLase designs, develops, and manufactures an ultra-fast laser that is revolutionizing refractive and corneal surgery by creating safe and more precise corneal incisions. Delivering on the promise of ophthalmic laser technology, the IntraLase FS laser, related software, and disposable devices replace the hand-held microkeratome blade used during LASIK surgery. The unsurpassed accuracy of IntraLase's computer-controlled femtosecond laser has been shown to improve safety profiles and visual outcomes when used during LASIK. Additionally, the IntraLase FS laser creates precision-designed intracorneal incisions that when combined can be used during lamellar and penetrating keratoplasty, and intrastromal ring implantation. IntraLase is presently in the process of commercializing applications of its technology in the treatment of corneal diseases that require corneal transplant surgery. The company's proprietary laser and disposable patient interfaces are presently marketed throughout the United States and 32 other countries.
