An electromagnetic radiation beam is inputted into a ring interferometer rotating at the angular velocity &#x3a9; where the beam is split into two equally intensive counter&#x2014;propagating electromagnetic beams. The Sagnac Effect results in the phase shift of &#xb1;Pi/2 radians, which may be either positive or negative depending on the direction in which the counter-propagating electromagnetic radiation beams propagate with regard to the rotation direction of the ring interferometer. An additionally phase shift of Pi/2 radians is induced between the counter-propagating electromagnetic radiation beams inside the ring interferometer results in a total phase shift of either Pi radians or 0. The counter-propagating electromagnetic radiation beams inside the ring interferometer are then combined into one single electromagnetic radiation (EMR) beam which outputted from the rotating ring interferometer by using a different path than the one through which the EMR beam is inputted into it.

This invention relates to the field of laser technology and more particularly to the ultra-short pulse generation methods and generators. One round trip of the ultra-short light pulse formation inside a generator optical loop comprises these steps: amplification of the light pulse, spectral broadening of the amplified light pulse due to the optical Kerr effect inside the optically transparent medium, selection of the predeterminated spectral components of the spectrally broadened light pulses by using the first spectrally-sensitive optical element, then again follows amplification of the selected light pulses, spectral broadening of the amplified light pulse due to the optical Kerr effect inside the optically transparent medium and selection of the predeterminated spectral components of the spectrally broadened light pulses by using the second spectrally-sensitive optical element, where spectral components of the light pulses selected using the first spectrally-sensitive optical element are different than the spectral components of the light pulses selected using the second spectrally-sensitive optical element.
