(a) Visualization of all obtained stable regimes obtained during the PSO algorithm execution. Each blue dot on the graph corresponds to a certain laser output with the given bandwidth and pulse width. Red crosses denote the target parameters that were set to the PSO algorithm. (b) Colored dots correspond to the boundaries (in the space of parameters) of the regimes, the energy of which does not exceed 1.2 nJ (blue dots), 1.6 nJ (orange dots) and 2.0 nJ (green dots). Lines have been obtained as the approximation by polynomials of the 5th degree for each set of these points. Inset shows spectrum and temporal profile corresponding the the red circle (bandwidth of 15 nm and pulse width of 10 ps).
