Excimer Lasers
Photochemical - break bonds
angioplasty (XeCl - 308 nm)
- spectroscopic or ultrasonic techniques to distinguish artery from plaque (smart lasers)
radial keratotomy - flattening cornea to correct nearsightedness
- less than 1 mm thermal damage for 193 nm ArF
teeth - pulpal temperature rise should be no more than 5 degrees C
- therefore, photochemical type laser may be best
