Abstract

We demonstrate that two white-light continuum pulses that are independently generated by phase-locked ultrashort laser pulses are locked in phase and show surprisingly clear and stable Young interference fringes. The experiment shows that the two generated continua emit essentially in phase and that random phase jitter can remain negligible. This result is not only of interest for studies of nonlinear field–matter interactions but also suggests that such white-light continuum pulses can be used to realize a broad frequency comb for absolute frequency measurements from the IR to the UV.

Figures (3)

Fig. 1
Fig. 1

Experimental setup for testing the phase lock between two white-light continuum pulses. The IR pulses from the laser are split by a 50% beam splitter (BS) and focused with a variable relative delay by lens L onto a thin CaF2 plate. Interference fringes between the two emerging continua are detected on a screen in the far field.

Fig. 2
Fig. 2

White-light fringes resulting from the interference of the two continua generated by the two phase-locked IR laser pulses when the relative delay is properly adjusted to zero.

Fig. 3
Fig. 3

Spectrally dispersed white-light fringes. Clear and well-defined fringes indicate that a stable phase relationship is conserved across all the generated visible spectrum.
