Pulse compression and spatial phase modulation in normally dispersive nonlinear Kerr media.

Numerical simulations show that, because of the spatiotemporal coupling implied by the multidimensional nonlinear Schrödinger equation, self-focusing of ultrashort optical pulses can lead to pulse compression even in the normal-dispersion regime of a nonlinear Kerr medium. We show how this coupling can be further exploited to control the compression by use of spatial phase modulation. Both the ...

Chirped-Pulse Oscillators: Route to the Energy-Scalable Femtosecond Pulses

In the last decade, femtosecond pulse technology has evolved extremely rapidly and allowed achieving a few-optical-cycle pulse generation directly from a solid-state oscillator (Brabec & Krausz (2000); Steinmeyer et al. (1999)). Applications of such pulses range from medicine and micro-machining to fundamental physics of light-matter interaction at unprecedented intensity level and time scale (...

Nonsoliton Pulse Evolution in Normally Dispersive Bers

For a typical NRZ pulse propagating in existing normally dispersive bers, we provide a uniform description of the optical transmission. There are three distinct regimes of the governing nonlinear Schrr odinger equation: the fully nonlinear dispersive regime (ND), which covers a small region of the pulse; and two limiting asymptotic regimes-nonlinear, weakly dispersive (ZD) (for the bulk of the ...

Self-compression of ultrashort pulses through ionization-induced spatiotemporal reshaping.

We present the first demonstration of a new mechanism for temporal compression of ultrashort light pulses that operates at high (i.e., ionizing) intensities. By propagating pulses inside a hollow waveguide filled with low-pressure argon gas, we demonstrate a self-compression from 30 to 13 fs, without the need for any external dispersion compensation. Theoretical models show that 3D spatiotempor...

Measurement of net group and reshaping delays for optical pulses in dispersive media.

We experimentally demonstrate the direct measurement of net group and reshaping delays for arbitrary optical pulses in dispersive media, verifying the earlier prediction of Peatross et al. [Phys. Rev. Lett. 84, 2370 (2000)]. Incoherent pulse propagation in an absorptionless system is well described by net group delay; even the medium causes a great deal of deformation in the transmitted pulse. ...
