She enabled passively modelocked optically pumped semiconductor disk lasers (i.e. VECSELs and MIXSELs) with her SESAM technology. The SESAM technology also allowed the invention of two new methods for multiplexing a single cavity to support a pair of pulse trains with different pulse repetition rates ideally suited for dual-comb applications. In time-resolved attosecond metrology highlight achievements are the invention of the attoclock which measured the electron tunneling delay time, observed the dynamical Franz-Keldysh effect in condensed matter, and measured attosecond photoemission time delays from atoms and molecules using coincidence detection and angular resolution for the first time.
