Working principle:
Capella is based on spectral division of a coherent supercontinuum into three different bands (channels) by chirped dichroic beamsplitters [1]. Using an interferometric spatio-temporal superposition a field waveform can be controlled and synthesized. All constituent pulses from the channels of CAPELLA are temporally compressed by chirped mirrors down to pulse duration of <10 fs. Introducing different time-delays among the channels enables the shaping and sub-cycle control of the field waveform [2].

Center: Parallel channel compression and temporal overlap with attosecond resolution.
Right: Passive interferometric stability between different channels over more than an hour.
Due to its solidness, compactness and excellent thermal capabilities, CAPELLA can maintain the optical pathlength stable among the different channels for many hours. Furthermore, an extra active-controlled loop improves the interferometric stability to <50 mrad. Apart from the generation of waveforms, CAPELLA offers the shortest pulses available in market to date, see below:
