Subfemtosecond Pulse Generation by Molecular Modulation
نویسندگان
چکیده
We suggest a technique for producing subfemtosecond pulses of radiation. The technique is based on using electromagnetically induced transparency to produce a strongly driven molecular coherence. This coherence results in a Raman spectrum with Bessel function amplitudes and phases corresponding to a frequency modulated signal, thereby allowing compression by the group velocity dispersion of the same medium.

Subfemtosecond pulse generation by rotational molecular modulation.
We extend a recent suggestion for the generation of subfemtosecond pulses by molecular modulation [Phys. Rev. Lett. 81, 2894 (1998)] to the rotational spectrum of molecular hydrogen (H(2)) . When a rotational transition |a? ? |b? is strongly driven (|rho(ab) |=0.5) the generation and phase-slip lengths are of the same order and the Raman spectrum has approximately Bessel function sideband ampli...
متن کاملUltrashort pulse generation by molecular modulation
This PhD Tutorial describes a new source of coherent radiation, with a spectrum extending over many octaves of optical bandwidth. We demonstrate collinear generation of mutually coherent spectral sidebands, ranging in wavelength from 2.94 μm in the infrared to 195 nm in the ultraviolet. The pulse energies are above 1 mJ/10 ns pulse for each of the nine central sidebands. The essence of our tech...
متن کاملBroadband Light Generation in Raman-active Crystals Driven by Femtosecond Laser Fields
Short pulse generation requires a wide phase-locked spectrum. Earlier the short pulses were obtained by expanding the spectrum of a mode locked laser from self phase modulation (SPM) in an optical fiber and then compensating for group velocity dispersion (GVD) by diffraction grating and prism pairs. Pulses as short as 4.4 fs have been generated (Steinmeyer et al., 1999). For ultrafast measureme...
متن کاملSpace Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
متن کاملThe Attosecond Lighthouse in Gas: Isolated Attosecond Pulses generation and Physical Dynamic probing
Through high-harmonic generation, attosecond pulse train can be produced with half-cycle temporal separation. Each pulse in this train carries information on physical processes in the medium during its generating time. Here, the spatially chirped laser pulses are used in high-order harmonics generation experiment to get a train of isolated attosecond pulses angularly separated—an attosecond lig...
