  • Patent number: 11389240
    Abstract: A laser ablation device which, an emitting double ring beam at the tip, is used in treatment, without permanent damage and scar, of natural diseases like venous insufficiency, of subsequently-formed diseases like fistula or of hemorrhoids formed as damaging of the vein. The device includes a fiber probe with two different conical angled surfaces where the rays guided through inside the fiber are reflected at the fiber tip via a first conical shaped-end formed at a first specific angle at the fiber's tip and a second conical shaped-end formed at different second specific angle by starting from a certain portion of the first conical shaped-end.

  • Publication number: 20090213877
    Abstract: A fiber laser for the production of self-similar pulses contains a pumped source and a linear resonator. The linear resonator has two reflectors. The laser further includes a polarization-maintaining fiber doped with an amplifying medium with a normal dispersion ?2>0 in the frequency range prescribed by the amplifying medium and a dispersion-compensating element with an anomalous dispersion ?2<0. The laser further includes an element for decoupling radiation and a non-linear mode coupling element with a modulation depth >0. The fiber, dispersion-compensating element, element for decoupling radiation and non-linear mode coupling element are disposed between the two reflectors in a common beam path delimited by the resonators. The total dispersion of the components disposed in the beam path of the resonator is normal.
