Abstract:
1. A method for emitting optical pulses in view of a desired output energy thereof and an external trigger signal defining trigger pulses at a variable trigger period, the method using a laser system having a seed laser oscillator optically coupled to one or more cascaded optical amplification stages, the method comprising: g) providing, for each of the amplification stages, a plurality of sets of pump pulse parameters each associated with specific values of the output energy and the trigger period; h) receiving said desired value of the output energy and said trigger signal; for each of the trigger pulses in the received trigger signal; i) measuring a current value of the trigger period; j) selecting, for each of the amplification stages, the pumping parameters associated with the received desired value of the output energy and the current value of the trigger period; k) sending a pump pulse to each of the amplification stages according to the corresponding selected pump pulse parameters; and l) launching a seed pulse from the seed laser oscillator for propagation through the amplification stages after the pumping thereof.
