Self-phase modulation in chirped-pulse amplification.
The effect of self-phase modulation in chirped-pulse amplification is investigated. A numerical model is used to predict the effects of phase modulation on pulse recompression, and experimental results are presented that agree well with the calculations. We show that even moderate self-phase modulation can significantly distort the recompressed pulse after amplification, thereby reducing the pe...
متن کاملRemoving cross-phase modulation from midinfrared chirped-pulse upconversion spectra.
We observe that narrow spectral features in mid-infrared spectra obtained by chirped-pulse up-conversion are strongly distorted by cross-phase modulation between the mid-infrared field and the chirped pulse. We discuss the consequences of this effect on spectral resolution, and introduce a correction method that recovers masked lines. This simple correction can be applied either when the upconv...
متن کاملAn alexandrite pumped Nd:glass regenerative amplifier for chirped pulse amplification
For many high field physics studies a laser source capable of producing intensities of 1017 W/cm 2 or greater is necessary. Ideally, such a laser source should be compact and simple so that it is at once reliable and manageable. In order to make the laser as compact as possible it is extremely desirable to use solidstate amplifier materials because of their energy storage capability. If this en...
متن کاملModulational Instability in a Communication Link Exploiting a Negative Nonlinearity for Compensation of Self-phase Modulation
In optical communication systems, the technique of alternating dispersion is commonly used as a way to counteract the dispersive pulse broadening. The main limitations, in terms of bit-rate, then come from the fiber Kerr nonlinearity acting through self-phase modulation and four-wave mixing [1]. The recently introduced method of " dispersion management ", where the dispersion compensation is on...
متن کاملNd:glass diode-pumped regenerative amplifier, multimillijoule short-pulse chirped-pulse-amplifier laser.
We have built a diode-pumped Nd:glass regenerative amplifier that is able to produce energies up to 20 mJ within a 470-fs pulse duration at a 1-Hz repetition rate. We obtained this amplifier by using specific intracavity components such as a phase mirror and a birefringent filter to generate a large spatial mode and a large spectral width.
