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.
