Characteristic Tissue Fluorescence Induced by XeCl Excimer Laser Ablation

Fluorescence radiation is induced following ablation of tissue by a 308nm wavelength excimer laser pulses. This fluorescence is determined by the composition of the ablated tissue, mainly minerals and proteins. The fluorescence is guided retrograde through the ablation fiber to an optical multichannel analyser (OMA), spectroscopically analysed on-line using a PC, and stored.
