Method and spiral cutting a glass tube using filamentation by burst ultrafast laser pulses


A method of producing a spiral cut transparent tube using laser machining includes using an ultrafast laser beam comprising a burst of laser pulses and focusing the laser beam on the transparent tube to enable relative movement between the laser beam and the transparent tube by moving the laser beam, the glass tube or both the laser beam and the glass tube. A beam waist is formed external to the surface of the transparent tube wherein the laser pulses and sufficient energy density is maintained within the transparent tube to form a continuous laser filament therethrough without causing optical breakdown.
