Self-organized bundle of lasing filaments in dense media

The filamentation of powerful, ultrashort laser pulses in liquids is investigated. It is shown that the multiple filaments produced in ethanol can be modified into controllable, regular patterns by doping the medium with dyes at high concentrations. Experimental results are confirmed by three-dimensional numerical simulations. Pump-dump pulse experiments furthermore reveal that the stimulated emission from excited dye molecules in the bundle can be locked in phase and leads to bright interference patterns.
