<p>A radiation source (100, 200) adapted for providing high order harmonic radiation (HHG radiation), in particular in an UV or XUV wavelength range, comprises a resonant cavity (10, 20) adapted for guiding laser light pulses, the resonant cavity including at least two cavity mirrors (11, 12, ..., 21, 22 ...), a first non-linear medium (30) adapted for providing the HHG radiation by harmonic generation based on an interaction of the laser light pulses with the first non-linear medium (30), wherein the first non-linear medium (30) is arranged in the resonant cavity (10, 20) in an environment of reduced pressure, and a second non-linear medium (50) which is arranged in the resonant cavity (10, 20)and is adapted for at least one of an amplification of the laser light pulses and phase locking of longitudinal modes of the laser light pulses in the resonant cavity (10, 20). Furthermore, a method of high order harmonic generation of pulsed radiation (HHG radiation) using the radiation source (100, 200) is described.</p> |
