Modular high-energy widely tunable provide ultra-high-speed fiber source

摘要

A fiber - based chirped - pulse - the amplification system, which output pulses in the wavelength range between 1 μm – 1,15 generated, with:a nucleus source (1), which is a passively mode-locked yb - fiber optic laser comprises;a yb - fiber amplifier (3a) for amplifying an output of the fiber laser;a fiber pulse elongation a direction (2), which the pulses from the nucleus source, the pulses and dispersive manner with respect to time, the expanded pulses at the fiber amplifier, wherein the fiber pulse elongation a direction (2) at least one of a bragg - fiber - grating and a fiber - transmission grating comprises;an optical modulator (52), which is connected between the passively mode-locked fiber laser and the yb - amplifier is arranged, wherein the modulator can be controlled in order to the repetition rate of pulses which are output by the mode coupled fiber laser, and in order to reduce the available pulse energy of pulses, which with the yb - amplifier are amplified, to increase;a pulse - compacting device (4), which the amplified stretched..
