Abstract

The wavelength dependence of the ablation threshold of a variety of tissues has been studied using a tunable pulsed Co:MgF2 laser in order to determine how closely it tracks the optical absorption length of water. The Co:MgF2 laser was optically pumped by a Nd:YAG laser emitting at 1.338 μm. Typical output energies were 70 μJ in a train of 2-JAS pulses approximately 100 μs long. The Co:MgF2 laser was tuned between 1.81 and 2.14 μm, a wavelength region in which the absorption length varies by a decade.
