Tunable ans stable ultrashort laser pulses in the visible spectrum are generated with high efficiency by four-wave-mixing process during filamentation of near-infrared and infrared laser pulses in gases. It is shown [1] that these tunable ultrashort pulses have a very low energy fluctuation and an excellent mode quality due to the processes of intensity clamping and self-filtering in the filament.
