WitrynaImpulsive stimulated light scattering (ISLS) offers an al- ternative, time-domain approach to determining the acoustic properties of materials under high pressure.6Although some- what lower in... The Raman-scattering process as described above takes place spontaneously; i.e., in random time intervals, one of the many incoming photons is scattered by the material. This process is thus called spontaneous Raman scattering. On the other hand, stimulated Raman scattering can take place when some Stokes photons have previously been generated by spontaneous Raman scattering (and somehow forced to remain i…
