We studied the irradiation of silver enriched soda-lime glass slides by 6 nanosecond long laser pulses at the wavelengths of 1064 and 532 nm. The extinction spectra of the irradiated glass regions after the laser exposition and after chemical and reactive ion etching (RIE) were compared. Independently on the wavelength, the irradiation resulted in the formation of silver nanoparticles demonstrating localized surface plasmon resonance (LSPR), which gradually disappeared with the etching of the samples. The dependence of the spectral position of LSPR on the etching time was significantly different for chemical etching and RIE. We relate this to the chemical interaction of silver with the gases used in RIE.
