Abstract
A Raman system uses a semiconductor tunable laser subsystem to generate a tunable signal that is tuned over a scan band of greater than 50 nanometers. A probe system transmits the tunable signal to a sample. Finally a detector system comprises a bandpass filter for filtering a Raman signal from the sample generated by the tunable signal, and a detector for detecting the filtered Raman signal.
