Raman Probes Shape Up

A method in which a probe pulse is delayed and has its shape optimized so to minimize the nonresonant background contributions may enable many practical applications of Raman spectroscopy previously determined impracticle. Raman spectrscopy is a technique that can provide a wealth of information about molecular vibrations and provide fingerprint-like signatures for identification, but even when signal strength is boosted by coherently exciting the vibrations with laser pulses, a fluctuating background signal hindersin sensing.
