Phys. Rev. Lett. 83, 2560–2563 (1999)Generation of Multiple Phase-Locked Stokes and Anti-Stokes Components in an Impulsively Excited Raman MediumReceived 10 May 1999; published in the issue dated 27 September 1999 We report on the observation of a highly efficient transformation of laser radiation into higher-order Stokes and anti-Stokes components in impulsively vibrationally excited gaseous SF6. The specific (Bessel-like) behavior of their intensity with the gas pressure reveals the mutual coherence of the generated frequencies. We propose this new regime of Raman frequency conversion for generation of sub-fs pulses. © 1999 The American Physical Society URL:
