Description of the thesis topic
Description the thesis subject The CORIA laboratory opens a PhD position under a Labex EMC3 (French National/Regional program) grant in the field of ultrafast optics.
Real-time optical measurement techniques now allow the capture of ultrafast phenomena for which no standard monitoring system is available and thereby open a myriad of new possibilities in the field of optical metrology. This PhD thesis is thus organized along two main axes, one more fundamentalnand the other more applied. On the one hand, the aim will be to develop and/or perfect ultrafast measurement techniques and to implement them on the innovative laser sources developed in the lab (fiber lasers, parametric oscillators [1,2], and other ultrafast sources ) in order to investigate their shot-to-shot dynamics. On the other hand, these techniques will be oriented towards original applications in single-shot imaging  notably for the study of laser-induced plasmas and also the exploration of various ultrafast phenomena encountered during matter analysis by tomographic atom probe (TAP).
