    Abstract: PROBLEM TO BE SOLVED: To provide a device for dispersing light pulses in which relative amplitudes of pulses at various wavelengths can be modified over time. SOLUTION: The device for dispersion of light pulses of an optical beam (Fi) is composed of two dispersive prisms (P 1 , P 2 ), with the same vertex angle (α), mounted head to tail, the optical input surface of the first prism (P 1 ) being parallel to the optical output surface of the second prism (P 2 ), and the distance (L) separating the optical input surface of the first prism (P 1 ) from the optical output surface of the second prism (P 2 ) being adjustable, wherein the material constituting at least one of the first and second prisms (P 1 , P 2 ) is an acousto-optic material allowing for acousto-optic interaction between the optical beam and an acoustic beam, and the acoustic wave of the acoustic beam generates an integrated deflective Bragg cell in at least one of the first and second prisms (P 1 , P 2 ).

    Abstract: PROBLEM TO BE SOLVED: To provide a method for high-resolution acousto-optic programmable filtering in an infrared region of incident optical wave.
    SOLUTION: A birefringent acousto-optic crystal(TR) is used, wherein the propagation speed of acoustic waves is slow, such as compounds of mercury. The acousto-optic crystal comprises, on one of its faces, a piezoelectric transducer designed to generate a transverse acoustic wave with wave vector(K) whereof the energy propagates according to the same axis(▵) but in the opposite direction to the energy of the incident optical wave(O
    i ), knowing that the optical wave(O
    d ) resulting from the acousto-optic interaction between the incident optical wave and the acoustic wave with wave vector(K) is diffracted perpendicularly or almost perpendicularly to the direction of the incident optical wave(O
    i ).

    Abstract: The invention relates to a method and device for controlling the amplitude of the wavelength spectrum of ultra-short light pulses emitted by multipass laser amplifiers. According to the invention, a programmable acousto-optic device (8) is introduced into a laser cavity of a multipass amplifier (10), in order to modify slightly the amplitude of the spectrum of the light pulse with each passage, owing to a collinear or quasi-collinear interaction between the light pulse and a sound beam, the result from the filtering being used on the non-diffracted direct light beam from the acousto-optic interaction.
