High harmoni generation giant resonance xenon
Web1 de fev. de 2012 · A simple modelocked femtosecond laser does not emit powerful enough pulses for ordinary high harmonic generation. A recent experiment has shown that amplification and pulse compression of pulses from a Yb:KGW laser modelocked at 20.8 MHz can produce high harmonics when focused into a xenon jet, but so far powers are … Web4 de mar. de 2015 · We perform second harmonic generation (SHG) spectroscopy as a function of laser energy and polarization at T =4 K. At the exciton resonance energies we record an enhancement by up to 3 orders of magnitude of the SHG efficiency, due to the unusual combination of electric dipole and magnetic dipole transitions.
