Raman spectra recorded in a non-irradiated spot and on crater walls formed upon single-shot pulsed laser irradiation of UDMA polymer samples without (UDMA-X—left) and with (UDMA-Au1—right) gold nanorods with ultrashort laser pulses of different energy. The left part of each graph shows the 2000–2650 cm-1 region enlarged for clarity.
