The Raman probe incorporates both excitation and
collection optics, and localized laser processing is performed using pulsed laser light delivered to the
specimen via the tapered optical fiber. Precise positioning of the fiber is achieved using a nanomanipulation
stage in combination with simultaneous electron-beam imaging of the tip-to-sample distance.
Materials modification is monitored in real time by transmission electron microscopy. First results obtained
using the assembly are presented for in situ pulsed laser ablation of MoS2 combined with Raman
spectroscopy, compliment by electron-beam diffraction and electron energy-loss spectroscopy
