The polarization plane of the uncoupled beams (2a/2b) is adjusted with regard to the subsequent optical elements and one of the polarization components of one of the partial beams is delayed in a fixed and defined manner (3Ä). Two polarization components of both partial beams, corresponding to the selected type of OPA interaction, are then together and synchronously directed to at least one anisotropic nonlinear medium exhibiting the OPA phenomenon (4x/4y) in which the partial signal beam is amplified and the idler wave is generated. The measuring element then measures and compares the individual intensities of both pulse polarization components of the signal wave and/or idler wave (5x/5y) and based on this evaluation, the feedback loop for the synchronization is implemented (A~B). From a laser oscillator (1) a chirped femtosecond probe pulse (8) is derived as well as pump pulse (9). The jitter stabilisation between these two pulses is performed with the help of a controlled delay line (4) and the pump pulse is amplified in a subsequent regenerative amplifier (2). Part of the amplified pump pulse (10) and the probe pulse is directed to a OP-CPA (3). The remainder is directed to a jitter stabilisation system (6).
