Generation of 3.8-fs Pulses Through Adaptive Cascaded Hollow Fiber Compressioned spectral region. However, it was only recently that a high-energy supercontinuum from two cascaded hollow fibers with bandwidths exceeding 500 THz was generated . The remaining challenge is then to compress these enormous bandwidths to finally yield an . ultrashort optical pulse.

0342-4111 n selected to provide an overview of the current state of the art. The purview of the field is the methods for the generation, amplification, and characterization of electromagnetic pulses with durations from the pieo-to the attosecond range, as well as the technical issues surrounding the applicati

A Robust New Concept for Octave-Spanning Chirped Mirrors with Minimal Dispersion Rippleo the sub-5-fs regime have only been possible by improved dispersion compensation, be it by using chirped mirrors , liquid-crystal phase modulators in a zero dispersion delay line , or Raman sideband generation . However, neither method has been demonstrated with spectra exceeding a

Broadband Phase-Coherent Optical Frequency Synthesis With Actively Linked Ti:Sapphire and Cr:Forsterears . The time-domain motivation for the push towards increased bandwidth is the generation of optical pulses that approach the single-cycle regime and can be used for phase-sensitive nonlinear experiments . The frequency-domain motivation is the interest in extending the bandwidth over whi

Synthesis of Optical Frequencies and Ultrastable Femtosecond Pulse Trains from an Optical Reference ownconverts the petahertz oscillation rate into countable ticks at 1 GHz. When compared to current microwave standards, these new optical clocks are expected to yield an improvement in stability and accuracy by roughly a factor of 1000. Furthermore, it is possible that the lowest noise microwave sou

Generation of 14.8-fs Pulses in a Spatially Dispersive Amplifierons of less than 10 fs, are exclusively generated by using gas-filled capillaries with subsequent chirped-mirror compression . Direct amplification of ultrabroadband laser pulses to high energies (millijoule region) still poses a challenging problem. Thermally induced lensing, gain-narrowing and
