Ti:sapphire regenerative amplifier for ultrashort high-power multikilohertz pulses without an external stretcher.
We report a simple and robust Ti:sapphire regenerative amplifier without prepulse stretching. Pulse stretching by positive group-velocity dispersion and negative third-order dispersion are provided by highly dispersive flint glass prisms inside the regenerative amplifier cavity. Using a single-grating compressor, we obtain transformlimited 60-fs Gaussian pulses at up to a 5-kHz repetition rate ...
متن کاملInvestigation of a grating-based stretcher/compressor for carrier-envelope phase stabilized fs pulses.
In this work, we experimentally investigate the effect of a grating based pulse stretcher/compressor on the carrier-envelope phase stability of femtosecond pulses. Grating based stretcher-compressor (SC) setups have been avoided in past demonstrations of chirped pulse amplification (CPA) of carrier envelope phase (CEP) stabilized femtosecond pulses, because they were expected to introduce signi...
متن کاملGeneralization of helicoidal beams for short pulses.
A generalization to the transient regime is developed for waves with a phase singularity of the screw type. These singular waves are commonly called vortices for all kind of waves as, for instance, optical vortex or acoustical vortex. We generalize the definition of vortices to get an azimuthal velocity invariant for all the frequency components contained in the broad spectrum of a short pulse....
متن کاملDiffractive Nonlinear Geometric Optics for Short Pulses
This paper considers the behavior of pulse-like solutions of length ε 1 to semilinear systems of hyperbolic partial differential equations on the time scale t = O(1/ε) of diffractive geometric optics. The amplitude is chosen so that nonlinear effects influence the leading term in the asymptotics. For pulses of larger amplitude so that the nonlinear effects are pertinent for times t = O(1), accu...
متن کاملStretcher-free high energy nonlinear amplification of femtosecond pulses in rod-type fibers.
We report on the study of direct amplification of femtosecond pulses in an 80 mum core diameter microstructured Yb-doped rod-type fiber amplifier in the nonlinear regime. The system includes a compact single grating compressor for the compensation of the small dispersion in the amplifier. With a 1250 line/mm (l/mm) grating-based compressor, pulses as short as 49 fs with 870 nJ pulse energy and ...
