    Abstract: The present invention relates to a device and a method for pulse modulation of laser pulses of tunable laser sources. The invention relates specifically to an arrangement for spectral and/or temporal laser beam manipulation of tunable lasers using nonlinear wave interaction. By using a variable, lens based beam forming section it is possible to manipulate a laser pulse provided by a tunable laser source (i.e. tunable in pulse energy, temporal pulse length and/ or wavelength) or different laser sources (i.e. different with respect to pulse energy, temporal pulse width and/ or wavelength) in such a manner, that nonlinear wave interaction can occur in the most efficient way. The beam forming section according to the invention allows for adjusting the waist of the laser beam and the focal position of the laser beam inside a cell comprising a nonlinear medium.

The system comprises a first laser source for generating a first laser output at a first frequency, a first second harmonic generator receiving as an input the first laser output to generate a frequency-doubled first laser output at a doubled first frequency, a second laser source for generating a second laser output at a second frequency different from the first frequency and a second harmonic generator receiving as an input the second laser output to form a frequency-doubled second laser output at a doubled second frequency. The system further includes a two-colour stabilisation arrangement to stabilise a sum of the doubled first and the doubled second frequencies that includes an interaction region incorporating a laser active material having a two-photon transition from a first energy level to a second energy level which receives as an input the frequency-doubled first laser output and the frequency-doubled second laser output where these outputs are selected to together cause the two-photon transition from the first energy level to the second energy level using an intermediate energy level to enhance the two-photon transition rate. The system also includes a detector to detect an indicator of the two-photon transition occurring in the interaction region which generates a frequency stabilisation signal for modifying either the first laser output or the second laser output to stabilise the sum of the doubled first frequency and the doubled second frequency to the two-photon transition based on the indicator and a stabilised optical output generator that includes a sum frequency generator receiving as an input the first laser output and the second laser output to generate a stabilised optical output with a frequency corresponding to the optical frequency standard.

    Abstract: A method and a pulse compressor (1) for compressing an optical pulse, wherein the pulse compressor comprising a bulk quadratic nonlinear medium (2) adapted for generating a negative nonlinear phase variation on the optical pulse and having a negative group-velocity dispersion, and a dispersive unit (3) with a net positive dispersion. Furthermore, the net positive dispersion in the dispersive unit at least partially compensates for the negative nonlinear phase variation and the negative group-velocity dispersion produced by the bulk quadratic nonlinear medium when the optical pulse passes through the bulk quadratic nonlinear medium and subsequently through the dispersive unit thereby generating a temporally compressed optical pulse. For 1 micron lasers second-harmonic generation at high intensities yields spectral broadening due to self-defocusing by the Kerr-nonlinearity which can subsequently be compressed by providing normal dispersion. As KDP crystals can be glued together, large apertures of the pulse compressor are possible making this method suitable for pulse compression in Joule-class lasers.
