Abstract (en)
[origin: WO2022171675A1] The problem addressed by the invention is that of providing an optical system which allows fluctuations in the pulse duration of ultrashort laser pulses to be detected quickly, sensitively and simply, and in a manner which makes it possible to derive an error signal for controlling the pulse duration from the detection. The invention solves this problem by means of an optical system having: a laser source (1), designed for generating pulsed laser radiation consisting of a chronological sequence of laser pulses; at least one dispersive optical element (4), designed to impress a group transit time dispersion and thus a chirp on the laser pulses; a non-linear medium (5), designed for the non-linear spectral broadening of the laser pulses during propagation through the medium (5); and a detection device (6), designed to detect the spectral broadening. The invention also relates to a method for generating laser pulses.
