摘要： The invention relates to a pulsed laser (10) with an optical fibre and frequency shifting for amplifying high-energy sub-picosecond pulses, including an oscillator (1), a fibre stretcher (3), one or more preamplification stages and one power amplification stage including an erbium doped or erbium-ytterbium codoped optical fibre section (4, 7), a pump (8) suitable for optically pumping by coupling in the optical fibre of the power amplifier (7) and a compressor (9). According to the invention, the pump (8) of the power stage generates at least one pump wavelength λP between 1530 and 1565 nm, the laser pulse emission wavelength (20) is between 1565 and 1625 nm and the energy of the laser pulses (20) is between 10 nJ and several dozen μJ. The invention also relates to a tool for eye surgery including such a laser.

摘要： The invention relates to an ultra-short high-power light pulse source including a first laser pump source (1), a mode-locking laser oscillator (2) a second laser pump source (4), a wave guide (6) capable of inserting spectral phases into the light pulses, and a compressor (8) capable of generating predetermined spectral phases into the light pulses. According to the invention, the wave guide (6) comprises a means capable of compensating the predetermined spectral phases generated at least by the compressor (8), the second laser pump source (4) being capable of delivering a second pump light flow (5) having a power PL such that the spectral phases generated by the wave guide (6) are opposed or quasi opposed to the predetermined spectral phases generated by the compressor (8) in order to generate compressed ultra-short light pulses (9) at the output of the compressor (8) with a planar or quasi planar spectral phase.

摘要： The present invention relates to a method and a passive device for the coherent combination of two amplified and/or spectrally broadened optical beams using at least one bidirectional optical component (A1, A2). According to the invention, the device comprises an amplitude division ring interferometer comprising optical splitting and recombining means disposed in such a way as to receive an incident optical beam (S
0 ) and to split it spatially into a first secondary input beam (H
1 ) and a second secondary input beam (H
2 ), optical guiding means disposed in such a way as to define an optical path in the form of a ring in said interferometer, the at least one bidirectional optical component (A1, A2) being disposed on the optical path of said ring interferometer, said splitting and recombining means being disposed in such a way as to receive and to recombine spatially, temporally and coherently said first secondary output beam (H
1 ") and said second secondary output beam (H
2 "), so as to form a coherent output beam.-

摘要： The invention relates to a passive device for the coherent combination of at least two optical amplifiers. According to the invention, said device comprises an interferometer having at least four branches (B1, B2, B3, B4) and comprising optical means for separating and combining polarisation, said means having four inlet-outlet ports that are respectively connected to a branch. The first branch comprises a first polarisation means, a first optical amplifier and a first mirror; the second branch comprises a second polarisation means, a second optical amplifier and a second mirror; the third branch comprises a third polarisation means and a third mirror; the fourth branch (B4) is an inlet-outlet branch of the interferometer; and the first, second and third polarisation means are designed such that a polarised optical beam entering respectively into the first, second or third branch and reflected by the mirror at the end of said branch forms a polarised optical beam that leaves said branch with a polarisation that is orthogonal to the polarisation of the polarised optical beam entering said branch.
