摘要：

The tuning of odd and even high-order harmonics of ultrashort pulses along the strong resonance of laser-produced indium plasma using an optical parametric amplifier of white-light continuum radiation (1250-1400 nm) allowed observation of different harmonics enhanced in the vicinity of the 4d(10)5s(21)S(0) -> 4d(9)5s(2)5p(1)P(1) transition of In II ions. We demonstrate various peculiarities and discuss the theoretical model of the phenomenon of tunable harmonics enhancement in the region of 62 nm using indium plasma. With the theoretical analysis we can reproduce the experimental observations and characterize the dynamics of the resonant harmonic emissions.
