Laser Induced Fluorescence in Atherosclerotic Plaque with Different Excitation Wavelengths

Spectroscopic characterisation of carotid atherosclerotic plaque by laser induced fluorescence

“…We have performed a comparative work on both visible and ultraviolet laser wavelengths and found evidence supporting the use of short pulsed excitation light [27]. One argument in favor of the nitrogen laser light, at 337 nm, is that as the light penetration depth is decreased in ultraviolet, we have a reduced interference from different plaque layers, resulting in acquisition of spectra with clear multiple peaks.…”
