DEVICE FOR GENERATING A SHORT, HIGH-ENERGY LASER PULSE, AND METHOD FOR GENERATING SUCH A PULSE |
摘要 |
The invention relates to a device (1) for generating a laser pulse, comprising: a fibre oscillator (10) generating a laser pulse (15); a nonlinear fibre amplifier (20) arranged to receive the laser pulse (15) generated by the fibre oscillator (10) and to generate a laser pulse (25) with energy amplified by a first factor; a solid-state, narrow gain bandwidth amplifier (30) arranged to receive the laser pulse (25) generated by the nonlinear fibre amplifier (20) and to generate a laser pulse (60) with energy amplified by a second factor, the device (1) being characterised in that the fibre oscillator (10) has a positive dispersion suitable for compensating the self-phase modulation of the nonlinear fibre amplifier (20), and in that the gain of the solid-state, narrow gain bandwidth amplifier (30) is suitable for suppressing the spectral pedestal of the laser pulse (25) received by the solid-state, narrow gain bandwidth amplifier (30). |
