Paper Abstract

A spectroscopic stone/ureter identification system is already in clinical use for pulsed dye laser lithotripters (590 nm). Alexandrite lasers are believed to be a solid-state laser alternative to pulsed dye lasers in lithotripsy. We investigated different spectroscopic stone/ureter detection schemes for the q-switched alexandrite laser (750 nm and 375 nm), including plasma detection, spectral LIF analysis, and time resolved LIF intensity analysis. Additionally, we investigated the possibility to identify different stone types using laser induced fluorescence exited at UV wavelengths.
