Abstract :
The possibilities of frequency combs generated by femtosecond lasers in ultra high precision spectroscopy on atomic hydrogen at the 10-14 accuracy level are explored. Fundamental tests of the fs frequency comb technique down to the 10-21 level are done. Further applications arise in the time domain where now the phase slip between carrier and envelope of such pulses can be controlled.
