Abstract

The medical laser market is with no doubt one of the most active with a very fast growth. The increase was led by a surge in both ophthalmic excimer systems and CO2 lasers for dermatology treatment and skin resurfacing. Specialty niches in dermatology (wrinkle removal, hair removal), urology (treatment of BPH), and ophthalmology (laser vision correction) continued to boost sales in 1997 and are likely to do so in 1998 (20% expected growth). The laser technologies that will benefit the most from these medical applications are ruby (hair removal), excimer (ophthalmology) and CO2 lasers (skin resurfacing). The control and the monitoring of the energy delivered by these lasers are critical for the success and the repeatability of the treatments. According to the application, lasers are used in Q-switched mode or long-pulse mode, we will present the both the suitable way to make in-situ measurement of the energy delivered by the laser. The second part of the presentation will focus on the on-line monitoring solution and its great advantages for the operator and the patient.
