We report the compression of intense, carrier-envelope phase stable mid-IR pulses down to few-cycle duration using an optical filament. A filament in xenon gas is formed by using self-phase stabilized 330 microJ 55 fs pulses at 2 microm produced via difference-frequency generation in a Ti:sapphire-pumped optical parametric amplifier. The ultrabroadband 2 microm carrier-wavelength output is self-compressed below 3 optical cycles and has a 270 microJ pulse energy. The self-locked phase offset of the 2 microm difference-frequency field is preserved after filamentation. This is to our knowledge the first experimental realization of pulse compression in optical filaments at mid-IR wavelengths (lambda>0.8 microm).

Isolated attosecond pulses and electron bunches can be efficiently generated in the interaction of intense lasers with plasma in the confined volume of the λ3 regime. Scaling with intensity is found to improve pulse brevity and focusability greatly while the efficiency of the attosecond pulse generation continues to remain high. Practical consideration of the tools needed to generate such pulses indicates that such interactions are surprisingly accessible. We mention some introductory experiments whereby we may verify the theoretical predictions of this new class of attosecond pulses. This technique may enable us to reach the Schwinger intensity 1029 W cm−2.

Theoretically, Raman-like soliton compression of mJ, 30-fs pulses is predicted. Initial experiments demonstrate 2 times compression of 1.3 TW/cm2 pulses under non-optimal conditions. The results agree closely with numerical simulations.

We report on the generation of carrier-envelope phase (CEP)-stabilized pulses with a relativistic intensity and a high-contrast ratio. The CEP stabilization is achieved with a jitter of 0.95rad from a 0.5kHz femtosecond laser pulses with a focal intensity of 2.6×1018W∕cm2 and a picosecond contrast of 2.5×10−9. CEP noise analysis shows that the beam pointing at the pulse compressor is a dominant factor of the CEP fluctuation with our laser system.

The development of intense, ultrashort, table-top lasers operating in the mid-infrared spectral region, offers many new avenues for strong-field physics. Atoms submitted to such radiation allow photoelectrons to acquire huge quiver energies well over an order of magnitude larger than the binding energy of the neutral. Consequently, many interesting phenomena arise. First, wavelength offers a convenient experimental knob to tune the ionization regime by controlling the Keldysh parameter. Second, high harmonic generation depends directly on the quiver energy and can, therefore, be pushed to unprecedented limits. Third, wavelength controls the spectral phase of harmonics, and hence the possibility to improve the generation of pulses in the attosecond regime. The use of long wavelength lasers is critical to studying high-order harmonic generation in condensed phase systems, because they facilitate harmonic generation within the transmission window of the material and increase the damage threshold. We review some of the recent discoveries in long wavelength driven high-order harmonic generation in the case of isolated atoms, bulk crystals, and liquid.

We describe an all-reflective interferometric autocorrelator designed to measure ultrabroadband optical pulses in the UV through IR spectral regions. By carefully choosing the device geometry we are able to obtain approximations for the nonlinear autocorrelation functions that reduce computation times to values acceptable for use in iterative pulse reconstruction schemes. We describe the optical design, autocorrelation functions, and present proof-of-principle experimental results measuring 20.6 fs pulses with a transform limit of 9.6 fs.

Using small amounts of optical energy, it is possible to drive matter with relativistic intensity. We show unique energy transport properties, X-ray production, and efficient attosecond phenomena coming from microscopic plasmas driven by precisely focused ultrashort pulses of light.

We report the self-compression of linearly and circularly polarized light pulses down to the few-cycle regime by self-guided beam propagation of intense 38-fs pulses in different gases with uniform density and with a pressure gradient.

Focusing several-cycle laser pulses to relativistic intensities in a lambda<sup>3</sup> volume on plasma of ~lambda scale-length leads to deflection of the radiation. Spatio-spectral measurements at I=1.5times10<sup>18</sup> W/cm<sup>2</sup> show relativistic deflection and spectral broadening
