“…To account for the frequency doubling process, the 389 nm light field strength is reduced to 5 × 10 6 V/m and the transform limited pulse length is increased to 65 fs, reflecting spectral narrowing due to phase matching limitations. Although for these simulations the spectral phase is assumed flat, the effect of pulse chirp is small in the case of multipulse excitation of a two-photon transition with a resonant intermediate state [26].…”

Prospects for precision measurements of atomic helium using direct frequency comb spectroscopy

Abstract. We analyze several possibilities for precisely measuring electronic transitions in atomic helium by the direct use of phase-stabilized femtosecond frequency combs. Because the comb is self-calibrating and can be shifted into the ultraviolet spectral region via harmonic generation, it offers the prospect of greatly improved accuracy for UV and far-UV transitions. To take advantage of this accuracy an ultracold helium sample is needed. For measurements of the triplet spectrum a magneto-optical trap (MOT) can be used to cool and trap metastable 2 3 S state atoms. We analyze schemes for measuring the two-photon 2 3 S → 4 3 S interval, and for resonant two-photon excitation to high Rydberg states, 2 3 S → 3 3 P → n 3 S, D. We also analyze experiments on the singlet-state spectrum. To accomplish this we propose schemes for producing and trapping ultracold helium in the 1 1 S or 2 1 S state via intercombination transitions. A particularly intriguing scenario is the possibility of measuring the 1 1 S → 2 1 S transition with extremely high accuracy by use of two-photon excitation in a magic wavelength trap that operates identically for both states. We predict a "triple magic wavelength" at 412 nm that could facilitate numerous experiments on trapped helium atoms, because here the polarizabilities of the 1 1 S, 2 1 S and 2 3 S states are all similar, small, and positive.

“…The self-calibrating capability of the comb permits accurate determination of atomic structure in alkali and alkaline earth atoms [19,20,21,22,23,24], as well as the investigation of multiple molecular transitions [25]. Furthermore, high-resolution quantum control can be achieved via spectral manipulation of frequency combs [26,27].…”

We demonstrate the use of an optical frequency comb to coherently control and entangle atomic qubits. A train of off-resonant ultrafast laser pulses is used to efficiently and coherently transfer population between electronic and vibrational states of trapped atomic ions and implement an entangling quantum logic gate with high fidelity. This technique can be extended to the high field regime where operations can be performed faster than the trap frequency. This general approach can be applied to more complex quantum systems, such as large collections of interacting atoms or molecules.

The optical frequency comb may become a crucial component in the field of quantum information science, where complex multilevel quantum systems must be controlled with great precision [14].In this Letter, we report the use of an optical frequency comb generated from an ultrafast mode-locked laser to efficiently control and faithfully entangle two trapped atomic ion qubits. The optical pulse train drives stimulated Raman transitions between hyperfine levels [15,16], accompanied by qubit state-dependent momentum kicks [17]. The coherent accumulation of these pulses generates particular quantum gate operations that are controlled through the phase relationship between successive pulses. This precise spectral control of the process along with the large optical bandwidth required for bridging the qubit frequency splitting forms a simple method for controlling both the internal electronic and external motional states of trapped ion qubits, and may be extended to most atomic species. This same approach can be applied to control larger trapped ion crystals with more advanced pulseshaping techniques, and can also be extended to a strong pulse regime where only a few high-power pulses are needed for fast quantum gate operations in trapped ions [17][18][19].High fidelity qubit operations through Raman transitions are typically achieved by phase-locking frequency components separated by the energy difference of the qubit states. This is traditionally accomplished in a bottom-up type of approach where either two monochromatic lasers are phase locked or a single cw laser is modulated by an acoustooptic (AO) or an electro-optic (EO) modulator. However, the technical demands of phase-locked lasers and the limited bandwidths of the modulators hinder their application to ex...

“…By using a comb laser, which means an ultrafast laser pulse train with a high repetition rate, one can carry out the ultrahigh resolution spectroscopy. Recently it has been shown that the accumulation ef-fects of coherence by a laser pulse train play an important role for coherent control of atomic or molecular systems [9,10]. The use of a chirped laser pulse train is another way for coherent control of population transfer [11].…”

We investigate the dynamics of a pair of short laser pulse trains propagating in a medium consisting of three-level Λ-type atoms by numerically solving the Maxwell-Schrödinger equations for atoms and fields. By performing propagation calculations with different parameters, under conditions of electromagnetically induced transparency, we compare the propagation dynamics by a single pair of probe and coupling laser pulses and by probe and coupling laser pulse trains. We discuss the influence of the coupling pulse area, number of pulses, and detunings on the probe laser propagation and realization of electromagnetically induced transparency conditions, as well on the formation of a dark state.
