Abstract: A method and a device for generating a series of laser pulses in a laser device, particularly single and multiple bursts of pulses with a minimum temporal distance between the pulses in a single burst in the picosecond domain. The device includes at least a master oscillator and a regenerative amplifier. The method includes steps of injecting a laser pulse from the master oscillator into the regenerative amplifier, amplifying injected pulse burst during multiple round-trips in an optical cavity of the regenerative amplifier, ejecting amplified pulse burst from the cavity of the regenerative amplifier. The injection step involves applying a first intermediate voltage to an optical switch for a time span, during which pulses from the oscillator are injected into the amplifier, forming a burst of injected seed pulses, which are further amplified in the amplification step, in which the optical switch voltage is set to a locking voltage.
