Abstract

The Vanderbilt free electron laser (FEL) operates between 2.0 and 8.0 micrometers with high peak intensities and a pulsed structure. Both the tunability of the FEL and the unique pulse structure make this an attractive tool for surgery. To be used effectively in surgery, one must be concerned with the control and delivery of the laser light from the FEL wiggler to the operating room. Several innovative delivery and monitor systems are being developed in our computer assisted surgical techniques (CAST) program at the FEL. To use the fastest pulse repetition rates and maintain minimal lateral thermal damage, a computer controlled scanning system is used. In the surgical applications of lasers, it is often necessary to know when a laser has penetrated a bone. We are developing a method to detect when the bone has been penetrated by measuring the photo acoustic signal generated by a pulsed laser.
