“…The results for Γ 1 for Yb, Tm and Er are in agreement within the errors with previously reported work. For Ho, both our measurement and the result of the Saffman group [35] are currently the only experimental estimates of the decay rate to metastable states. At present, no theoretical prediction is available.…”

“…To most simply explain our method, we focus the discussion on only one species, Ho. Miao et al [35] have recently reported laser cooling and trapping of Ho. We also refer the reader to work on MOTs of the other species: Yb [6], Tm [9] and Er [10,11].…”

“…In our quantum wave packet calculations, numerically solving 3D TDSE was conducted by our parallel computer code LZH-DICP [41] which was widely used to explore quantum dynamics processes of atoms and molecules in strong laser fields [42][43][44][45][46][47][48][49][50][51][52]. The laser electric field is linearly polarized along the z axis, and atomic units are used throughout this paper unless stated otherwise.…”

We present a theoretical investigation of high-order harmonic generation in spatially inhomogeneous two-color laser fields by solving three dimensional time dependent Schrödinger equation. The cutoff in the harmonic spectra can be significantly extended by means of our proposed method (i.e., from helium interacting with the plasmon-enhanced two-color laser fields), and an ultrabroad supercontinuum up to 1.5 keV is generated by selecting proper carrier-envelope phase of the controlling field. Moreover, classical trajectory extraction, time-dependent ionization and recombination rates, and time-frequency analyses are used to explain the generation of this ultrabroadband supercontinuum. As a result, an isolated 8.8 attosecond pulse can be generated directly by the superposition of the supercontinuum harmonics.

“…The interaction between intense laser pulses and atoms or molecules receives considerable attention [1][2][3][4][5], such as Coulomb explosion (CE) [6] and high-order harmonic generation (HHG). One of them, the HHG is well known due to the fact that it provides a new type of coherence light source of extremely short wavelength that can be widely used in many fields such as attosecond pulse generation [7][8][9][10][11], plasma spectroscopy [12], and X-ray fluorescence analysis [13].…”
