A laser device is provided for generating a helical-shaped optical wave and includes: (i) a gain region located between one first end defined by a first mirror and a second end defined by an exit region, (ii) a second mirror arranged so as to form with the first mirror an optical cavity including the gain region and a gap between the exit region and the second mirror, (iii) apparatus for pumping the gain region so as to generate the optical wave, wherein the laser device further includes at least one apparatus for shaping the light intensity and/or phase profiles of the optical wave and arranged for selecting at least one rotary-symmetrical transverse mode of the optical wave, the rotary-symmetrical transverse mode being chosen between those with a radial index equal to zero and with an azimuthal index being an integer with a module higher or equal to 1.
