The electron mass shift in a laser field has long remained an elusive concept. We show that the mass shift can exist in pulses but that it is neither unique nor universal: it can be reduced by pulse shaping. We show also that the detection of mass shift effects in laser-particle scattering experiments is feasible with current technology, even allowing for the transverse structure of realistic b...

This paper addresses data-aided (DA) synchronization, in which the reference parameter acquisition is aided by a training sequence known to the receiver. The Cramer–Rao lower bound (CRB) for the DA timing and/or carrier phase recovery is presented. For DA parameter estimation, the CRB typically varies with the training sequence. This indicates that different training sequences offer fundamental...

Two-photon absorption and blue-light-induced red absorption (BLIRA) is demonstrated in lithium tantalate LiTaO3 waveguides with ultrashort laser pulses. The blue transmission is modeled for hyperbolic-secantsquared pulses of blue light and is shown to be heavily attenuated by two-photon absorption. The blue light also generates traps for red light, which are absorbed through single-photon inter...

Based on the modified Kogelnik diffraction efficiency equation, we study the diffraction intensity spectrum and the total diffraction efficiency of reflection volume holographic gratings in photorefractive media. Taking photorefractive LiNbO3 crystal as an example, the effect of the grating parameters and the pulse width on the diffraction properties is presented under the influence of crystal ...

The capability to produce laser pulses of arbitrary temporal shape is important in areas of optical communication,' atomic and molecular spectroscopy~ and laserfu~ion.~ Previous pulse-shaping techniques have achievedmoderate success in these areas.44 The new approach discussed here, using the technique of spectral beam deflection (SBD), offers the potential of higher temporal resolution combine...

In this paper performance enhancement in PA measurements through optical pulse shaping is explored and demonstrated. A recently introduced setup, which is based on a CW tunable laser source operating in the optical communications band (1510-1620nm) and an electro-optic modulator, offers exceptional flexibility in controlling the temporal and spectral characteristics of the excitation waveform. ...

We theoretically and experimentally studied the dispersion effects in an actively mode-locked inhomogeneously broadened laser. In the positive group velocity dispersion (GVD) region, the laser generates incoherent pulses. Self-phase modulation and resonant dispersion impede reduction of the pulse duration when the GVD is small or near zero. A single, stable, soliton-like pulse can be generated ...
