...mirrors mounted on a fast and slow piezo crystal enabling rapid feedback and drift control simultaneously.

...as they may introduce phase jumps in the spectral regions where the stacks join, which will

Measuring broad spectra as they are emitted by the venteon oscillator series requires an intensity calibrated

...example, the dispersion of the beam splitter of a typical autocorrelator has to be compensated for

...fused silica would stretch the same pulse to approx. 20fs, the same as travelling through 2m

For extremely short pulses, such as few-cycle pulses, this can best be done with a combination
