Popis:	Nonlinear processing of glass using femtosecond laser pulses has been shown as a reliable method for producing photonic devices. To optimize the writing of optical waveguides and harness the true power of fs-laser modification, it is imperative that we gain a greater understanding of the physical mechanisms behind it. This requires experimental and theoretical studies into the dynamical processes during ultrashort laser–matter interaction. In this study, plasma emission spectroscopy and microscopy are shown as a reliable monitor for predicting the smoothness or roughness of the final laser-induced modification. Spectrally and temporally resolved optical transmission measurements using a supercontinuum probe beam are presented as experimental approach for investigating the transient optical properties of fs-laser-processed glass. The description of the light–plasma interaction is given by a simple model, which is used for inferring the order of magnitude of the electron density under such experimental conditions.
