Method and device for the production of stabilized ultrashort laser light pulses -

摘要

For the operation of a pulse laser (10) for the generation of laser pulses with a repetition frequency (f φ r, φ) is arranged a spectrum of n frequency components f φ n φ with f φ n φ = n been f φ r, φ + f φ 0 φ (n = 1 - n) contain (f 0 φ φ: offset frequency), in which with a repetition frequency - control circuit a first control signal for the repetition frequency setting and with an offset frequency - control circuit a second control signal for the offset frequency adjustment is produced, the laser pulses to a reference cell (33) directed in the case of a predetermined repetition frequency and a predetermined offset frequency an atomic transition is stimulated and a spectroscopic signal can be induced with a detector device (31) is detectable, with which a for the presence or absence of the spectroscopic signal characteristic output signal is generated, the output signal of the detector (31) for generating either of the first or the second actuating signal is used and the repetition frequency or the offset frequency of the pulse laser (10) is adjusted so that the output signal of the detector (31) indicates the occurrence of the spectroscopic signal.
