Abstract
The beam characteristics and spot geometry of a short pulsed (15 - 1000 microsecond) carbon- dioxide, multimode laser were measured. At a distance of 1.0 - 3.0 cm from the handpiece the laser produced a 5 mm2 square spot with an even fluence across the entire spot area (Mesa Mode). Human eyelid skin was irradiated both in vivo and ex-vivo immediately after excision with 1, 2, 3, or 4 pulses, a pulse duration of 62.5 microseconds, and at a fluence of 6 J/cm2. H&E stained sections showed an even removal of tissue across the impact site. The depth of thermal damage was measured as 38 micrometer plus or minus 22.7 with a range of 0 - 100 micrometer.
