International audienceWe review our recent results applying the stable nonlinear propagation of nondiffracting Bessel beams to femtosecond laser ablation in dielectric materials. We describe our spatial light modulator setup that allows for flexible and reconfigurable beam profile synthesis, we interpret the physics in terms of the formation of a steady plasma channel, and we present results of both multishot and single shot machining
