Note: Enhancement of the extreme ultraviolet emission from a potassium plasma by dual laser irradiation
Emission spectra from multiply charged potassium ions ranging from K(3+) to K(5+) have been obtained in the extreme ultraviolet (EUV) spectral region. A strong emission feature peaking around 38 nm, corresponding to a photon energy of 32.6 eV, is the dominant spectral feature at time-averaged electr...

| description | Emission spectra from multiply charged potassium ions ranging from K(3+) to K(5+) have been obtained in the extreme ultraviolet (EUV) spectral region. A strong emission feature peaking around 38 nm, corresponding to a photon energy of 32.6 eV, is the dominant spectral feature at time-averaged electron temperatures in the range of 8-12 eV. The variation of this emission with laser intensity and the effects of pre-pulses on the relative conversion efficiency (CE) have been explored experimentally and indicate that an enhancement of about 30% in EUV CE is readily attainable. |
