A process for operation of a laser device ( ) is described, whereby circulating light pulses each comprising spectral components according to a plurality of longitudinal modes of a resonator configuration ( ) are generated in the resonator configuration ( ) and subjected to a compensation of group velocity dispersion, and a predetermined linear dispersion is introduced into the light path of the resonator configuration ( ), so that at least one mode has a predetermined frequency and/or the mode distance between the modes has a predetermined value. Furthermore, regulations for stabilizing the laser device on the basis of this process and applications of the regulations for the generation for stabilized, ultra-short light pulses, generation of optical frequencies and in the frequency and/or time measuring technique as well as in the spectroscopy are described.

Generation of stabilized, ultra-short light pulses and the use thereof for synthesizing optical frequencies

A method for generating radiation with stabilized frequency, comprises the steps of providing laser light pulses with a repetition frequency f , said pulses comprising a plurality of N frequency components f with f &equals;n f &plus;f , wherein f represents an offset frequency with n&equals;1 , . . . , N, said frequency components forming a comb with first and second different frequency portions, and generating a primary light output with at least one output frequency component corresponding to the difference of frequencies of said first and second frequency portions.

Method and device for generating radiation with stabilized frequency

A device for generating and manpulating coherent matter waves contains a magnetic trap being adapted to form a magnetic trapping potential for gas atoms, said magnetic trap comprising a plurality of trap coils being connected with a current supply device and including two quadrupole coils and one Ioffe coil, wherein the trap coils are arranged in such a relative position that a common trap is formed, said common trap having a quadrupole trap shape with one trap minimum if the quadrupole coils are in an operation condition and the Ioffe coil is in a currentless condition or two trap minima or a Ioffe trap shape if all the quadrupole and Ioffe coils are in an operation condition and a shielding device protecting the magnetic trap against external magnetic fields. A method of continuous extracting matter waves from the trap is described.
