Abstract:
1. A method of generating intra-resonator laser light, comprising the steps of: coupling input laser light into an enhancement resonator, which comprises at least two curved resonator mirrors and which is free of a laser light amplifying medium, wherein said at least two curved resonator mirrors: (a) are consecutively arranged, (b) span at least one resonator path with a predetermined resonator length, and (c) provide at least two pairs of consecutive curved resonator mirrors which are serially coupled along said at least one resonator path; and coherent addition of the input laser light in the enhancement resonator so that the intra-resonator laser light is formed, wherein: (i) said at least two pairs of consecutive curved resonator mirrors each has a detuned concentric configuration; (ii) the input laser light comprises laser light pulses having a predetermined pulse repetition rate, pulse duration and carrier envelope offset frequency; and (iii) the intra-resonator laser light comprises at least one intra-resonator pulse circulating in the enhancement resonator.
