Soliton-similariton laser. Top: schematic of the soliton-similariton fibre laser. QWP: quarter wave plate; HWP: half wave plate; PBS: polarizing beamsplitter; WDM: wavelength-division multiplexer. Bottom: (a) and (b) show the spectra from simulation (red dashed) and experiment(black) from the 5% and 1% output ports. (b) also shows the output spectrum from the NPE port (broader, green dashed line). (c) and (d) show the pulse temporal profiles inferred from the PICASO algorithm [40] for the simulation and experiment at the 5% and 1% output ports. From [41].
