Abstract
A laser amplification arrangement comprising a laser medium for producing an amplified laser emission as output signal from a useful signal to be amplified and a pump source has a switching component for coupling the useful signal into the laser medium. Laser medium and switching component are formed and arranged so that a division of an input signal (ES) into the useful signal and a background signal is effected, the background signal being passed through the laser medium at a time immediately before and/or after the coupling-in of the useful signal to be amplified.
Claims15
A laser amplification arrangement, in particular for amplifying femtosecond and picosecond pulses, comprising at least
- a laser medium for producing an amplified laser emission as output signal (AS), in particular having an average power of more than 10 W or more than 100 W, from a useful signal to be amplified,
- a pump source, in particular a laser diode source, for pumping the laser medium,
- a switching component for coupling the useful signal into the laser medium,
- wherein laser medium and switching component are formed and arranged in such a way that a division of the input signal (ES) into the useful signal and a background signal is effected, in particular with the constant sum of useful signal power and background signal power, the background signal being passed through the laser medium at a time immediately before and/or after the coupling-in of the useful signal to be amplified.
A laser amplification method for an input signal (ES) to be amplified, in particular for amplifying femtosecond or picosecond pulses, comprising at least
- optical pumping of a laser medium,
- coupling of a useful signal to be amplified into the laser medium,
- production of an amplified laser emission as output signal (AS), in particular having an average power of more than 10 W or more than 100 W, by the laser medium,
- wherein a division of an input signal (ES) into the useful signal and a background signal is effected, in particular with a constant sum of useful signal power and background signal power, the background signal being passed through the laser medium at a time immediately before and/or after the coupling-in of the useful signal to be amplified.
