Abstract
A laser beam from a tunable solid state laser such as an alexandrite laser passes through a Raman shifter to produce a Raman-emitted beam with wavelength shifted so as to be able to activate a preselected photosensitizer for medical treatment. A combination of a laser and a Raman shifter with or without additionally a harmonic generator such as a frequency doubler may be also selected such that radiation with two different wavelengths can be obtained for treatment and detection.
