Interferometric Coherent Raman Spectroscopies with Incoherent Light: Time and Frequency Resolution via Radiation-Matter Oscillations
The study of dynamics through light/matter interaction has been pushed to ultrashort time resolution with the advent of femtosecond lasers. But in the early 1980’s  it was realized that apparently ultrashort timing could also be realized using light whose phase noise is sufficient to exhibit femtosecond scale autocorrelation times, even with nanosecond pulses. We have recently compared ultrashort timing with transform limited femtosecond light pulses (amplitude modulated light) and timing with incoherent light (phase modulated light), with abundant reference to the literature . The object of this report is to briefly summarize our findings.
