| Abstract: | Beginning with the coherent Raman amplification process,using simple quasi-equilibrium model and thermal elastic theory,it is conducted the theoretical analysis of photoacoustic Raman effect in solids.The expression for the PARS signal under pulsed laser excitation is derived and numerical estimate is made using typical values of the relevant parameters for a solid sample.The paper concludes with a discussion of some characteristics of PARS process in solids and a comparison to the situation in gases. |
| Keywords: | Solid Photoacoustic Raman effect PARS |
