High harmonic generation in rare gas solids

Placeholder Show Content


Strong-field laser excitation in semiconductors and insulators has been shown to produce high harmonic generation (HHG) and other strong field effects familiar in atomic physics. However, in solids, the microscopic processes underlying these effects are not well understood. One way of getting a better understanding is to compare HHG of a single chemical element both in solid and gas phase. In this dissertation I will discuss results of a comparative study of HHG is solid Ar and Kr and their respective gas states. We found that HHG spectra in solid Ar and Kr , which extends to about 40 eV, have secondary plateaus. In addition the cutoff law is well above the one in gas states. Both effects have origin from purely solid state effects. We use a quantum model of laser excitation to interpret our results and make a connection to past results on HHG in solid state, where the apparent differences between interband and intraband currents might just be stemming from vantage view. In addition, there are signs that manybody effects might play an important role in HHG in rare gas solids. Finally, the ellipticity dependence of HHG is as strong as in the case of gases which points to the importance of electron recombination. This means that HHG in solids can be a powerful tool for studying the microscopic and band structure of solids and their excitations.
