摘要:
A method of generating pulsed laser light (1) comprises the steps of providing laser light pulses (2, 3) having a predetermined pulse repetition rate (frep) with a laser source device (10), coupling the laser light pulses into an enhancement cavity (21) with a plurality of cavity mirrors (21.1, 21.2, . . . ) and a predetermined cavity length (L), and coherent addition of the laser light pulses (2) in the enhancement cavity so that at least one cavity pulse (1.1, 1.2, . . . ) is formed, wherein the at least one cavity pulse (1.1, 1.2, . . . ) circulating in the enhancement cavity (21) irradiates all of the cavity mirrors (21.1, 21.2, . . . ) with an angle (α) of incidence of more than 45°. Furthermore, a laser device (100) being configured for conducting the method is described.
摘要:
A radiation source that provides high order harmonic radiation (HHG radiation) in an UV or XUV wavelength range comprising a resonant cavity that guides laser light pulses that includes at least two cavity mirrors, a first non-linear medium that provides the HHG radiation by harmonic generation based on an interaction of the laser light pulses with the first non-linear medium, wherein the first non-linear medium is arranged in the resonant cavity in an environment of reduced pressure, and a second non-linear medium arranged in the resonant cavity and adapted for at least one of amplifying the laser light pulses and phase locking longitudinal modes of the laser light pulses in the resonant cavity.
