Patent ID: 7961772

Claim:
A laser system (x 01 ) comprising: pump generating means (x 02 , x 03 ) for generating at least a first and a second pump beam, lasing means (x 06 , x 07 ) for emitting radiation by being appropriately pumped, said lasing means (x 06 , x 07 ) being disposed in a first resonator so as to receive the first pump beam in order to generate a first beam (x 21 ) having a first frequency, and said lasing means (x 06 , x 07 ) being disposed in a second resonator so as to receive the second pump beam in order to generate a second beam (x 22 ) having a second frequency, at least one Q-switch (x 08 ; x 17 , x 18 ) being disposed in the first and the second resonator, so that the first beam and the second beam both pass a Q-switch (x 08 ; x 17 , x 18 ), and said laser system (x 01 ) having an output (x 13 ) generated from said first beam (x 21 ) and said second beam (x 22 ), wherein at least a part of said output (x 13 ) is fed back to a regulation system (x 14 ) comprising a comparator, a control system (x 31 ) and an optimization system (x 32 ), and wherein the control system (x 31 ) provides a first control signal, and the optimization system (x 32 ) provides a second control signal, to control the intensity output of the pump generating means (x 02 , x 03 ), thereby regulating the build-up time of individual laser pulses of the first beam (x 21 ) and second beam (x 22 ), respectively.
