“…Recently, we have proposed laser ablation microsampling (LAMS) to replace the traditional scalpel sampling. Focused single-pulse laser radiation has been used to take samples from paper materials [4,5], paint layers on a primed canvas [6], and the surface of fresco painting [7].

An original nonlinear optical method employing laser ablation with single nanosecond laser pulses at a wavelength of λ = 532 nm is used to study organic paint layer (copper phthalocyanine blue (PB15)). Two processes (photochemical reaction and formation of craters), which appear to be nonlinear result from the pulsed radiation. It is shown that the nonlinear optical procedure (laser ablation microsampling (LAMS)) can be used to obtain microparticles of PB15 sufficient for the further analysis. The Raman spectra of the surface of the paint layer prior to and after LAMS and microparticles are obtained. Spectral data, including those in the low-frequency region, are discussed.
