Pulse laser system that is temporally variable in terms of rhythm and/or amplitude

A temporally modulated in rate and/or amplitude pulse laser system, comprising:

• a first source comprising a mode-locking laser adapted to generate a source signal composed of source light pulses having a duration comprised between about 1 picosecond and a few hundreds of nanoseconds;
• an optical amplifier system adapted to receive and amplify said source signal,
• wherein the temporally modulated pulse laser system includes:
• a pulse selection or modulation device including a pulse selector or modulator arranged between the first source and the optical amplifier system, the pulse selector or modulator being configured to select or modulate the source signal so as to form a main signal composed of one or more source light pulses, the main signal being temporally modulated in rate and/or amplitude;
• a second source comprising a laser diode emitting a secondary signal comprising secondary light pulses having a duration of at least one nanosecond and
• the laser system being configured to inject simultaneously both the main signal as well as the secondary signal into said optical amplifier system, the optical amplifier system forming both an amplified main signal that is temporally modulated in rate and/or amplitude, as well as an amplified secondary signal,
• the secondary signal being modulated in real time as a function of the temporal modulation in rate and/or amplitude of the main signal, so as to stabilize the energy stored in the optical amplifier system as a function of time, and
• the laser system being configured to spatially separate, to a first output (S1), the temporally modulated in rate and/or amplitude amplified main signal, and, to a second output (S2,) the amplified secondary signal.
