Carrier-envelope-phase-stabilized femtosecond laser (CEP stabilized laser)

low 40 fs and a pulse energy of at least 1 mJ. In addition, it is a mandatory technical requirement that the system is carrier-envelope-phase-stabilised (CEP-stabilised), so that the phase between the oscillations of the laser field (“carrier”) and the pulse envelope (“envelope”) can be controlled.

CEP stabilisation is necessary for the planned experiments, as the experiments require reproducible control of the laser field phase with attosecond time precision. Without active CEP stabilisation, the planned experiments cannot be carried
