This study experimentally explores the fundamental aspects and complexities of femtosecond laser processing of dielectrics. Firstly, time-resolved microscopy investigates electron excitation, ablation, and heat-affected zone dynamics in dielectrics of photonic interest. Secondly, the role of laser wavelength (UV to MIR) is examined, determining aspects such as spatial resolution, ablation threshold, and maximum crater depth. Physical explanations, including simulations, are provided to elucidate their origins.
