Wave perspective on high harmonics amplification in a high-gain medium with level degeneracy
Amplification of a high-harmonic-signal in an amplifying medium of an Xray laser is analysed by applying Maxwell-Bloch equations. The model includes timedependent high swept-gain, randomized spontaneous emission component and laser level degeneracy. The output characteristics including energy extraction, pulse shape and polarization of the output radiation are obtained within the formulated model and discussed in detail.
