Abstract

We demonstrate an ultrafast transient, ring-shaped population grating induced by an ultrashort hollow Gaussian laser bullet by solving the three-dimensional full-wave Maxwell-Bloch equations. Through adjusting the beam waist and the area of the pulse, we can control the number of lines and the period of the grating. Based on this coherent control scheme, a door to produce gratings with complex transverse structure is opened.

Transient population and polarization gratings induced by (1+1) -dimensional ultrashort dipole soliton

Keyu Xia, Yueping Niu, Ruxin Li +2 more

An ultrafast transient population grating induced by a $(1+1)$-dimensional, ultrashort dipole soliton is demonstrated by solving the full-wave Maxwell-Bloch equations. The number of lines and the period of the grating can be controlled by the beam waist and the area of the pulse. Of interest is that a polarization grating is produced. A coherent control scheme based on these phenomena can be contemplated as ultrafast transient grating techniques.

Electromagnetically induced gratings created by extremely short non-overlapping pulses of light in a three-level resonant mediu

Rostislav M. Arkhipov

In a fixed spectral range, single- and half-cycle electromagnetic pulses have the shortest duration. Half-cycle pulses are promising tools for ultrafast control of quantum systems. Previously, the possibility of using a sequence of single- and half-cycle attosecond pulses to generate and ultrafast control light-induced population difference gratings has been demonstrated. However, such studies have been carried out using different approximations. For example, when the medium is modelled in the two-level approximation. In this paper, based on the numerical solution of the system of Maxwell-Bloch equations, it is shown that it is possible to generate and control population gratings in a three-level medium without using the approximations used in previous studies. It is shown that taking into account the additional level of the medium does not lead to a violation of the effect of generating such gratings. This extends the applicability of previous results.

Coherent Control of Extreme Nonlinear Optical Properties of Quantum System via Ultrashort Laser Pulses

Shangqing Gong, Keyu Xia, Yueping Niu +2 more

We investigate the extreme nonlinear optical properties of quantum system driven by ultrashort laser pulses by solving the one and two dimensional, full‐wave Maxwell‐Bloch coupled equations. We find that the near‐dipole‐dipole (NDD) interactions have a crucial influence on the absolute phase of few‐cycle laser pulses. The difference of the absolute phase between the cases with and without NDD effects can go up to π. Moreover, a novel ultrafast transient population grating induced by a two‐dimensional, ultrashort dipole soliton is demonstrated. The number of lines and the period of the grating can be controlled by the beam waist and the area of the pulse.

Analysis of laser-induced transient population gratings by different types of exciting pulse

Shuanggen Zhang, Shengdong Li, Yangbo Bai +1 more

Motivated by atomic response to different initial coherent optical fields, we comparatively studied transient population grating (TPG) induced by successive pulse train. Time delay and pump pulse duration dependence of TPG is achieved by numerically solving the density matrix equations. Results reveal that the creation and erasure of TPG is possible by choosing the appropriate pulse parameters, which is illustrated by Bloch sphere model and quantitative validation. To obtain desired large grating amplitude for rectangular pulse, the allowed pulse duration can be extended to one order wider than that of Gaussian pulse. Population grating can be erased to near zero by a third pulse with time delay by an odd multiple of half the pulse width, and it also can be erased further to recover atom assembly back to the initial state by a fourth pulse with time delay equal to an integer multiple of pulse width. Atomic behaviors excited by different types of pulse presented here may be significant to manipulate TPG during coherent light-matter interaction.

Subwavelength population density gratings in resonant medium created by few-cycle pulses

Rostislav M. Arkhipov, Mikhail V. Arkhipov, A. V. Pakhomov +4 more

We consider theoretically recently proposed a new possibility of creation, erasing and ultrafast control of population density grating. Such grating can be created in resonant medium when ultrashort pulses with duration smaller than relaxation times in the resonant medium (coherent light matter interactions) propagate without overlapping in this medium. Possible applications in the ultrafast optics such as optical switcher and laser beam deflector are discussed.

Population density gratings induced by few-cycle optical pulses in a resonant medium

Rostislav M. Arkhipov, A. V. Pakhomov, Mikhail V. Arkhipov +4 more

Creation, erasing and ultrafast control of population density gratings using few-cycle optical pulses coherently interacting with resonant medium is discussed. In contrast to the commonly used schemes, here the pulses do not need to overlap in the medium, interaction between the pulses is mediated by excitation of polarization waves. We investigate the details of the dynamics arising in such ultrashort pulse scheme and develop an analytical theory demonstrating the importance of the phase memory effects in the dynamics.
