Characterization of dynamic optical nonlinearities with pulse trains
نویسندگان
چکیده
We report a simple extension of the Z-scan technique where pulse trains characteristic of a Q-switched and mode-locked Nd:YAG laser are employed to investigate the dynamics of third-order optical nonlinearities. The method allows discriminating between fast and accumulative nonlinearities, and was applied to the investigation of liquid samples, namely chloroform, benzene, and a solution of Disperse Red 1 dye. © 1999 American Institute of Physics. @S0003-6951~99!03211-8#

Femtosecond synchronization of radio frequency signals with optical pulse trains.
A synchronization scheme for extraction of low-jitter rf signals from optical pulse trains, which is robust against photodetector nonlinearities, is described. The scheme is based on a transfer of timing information into an intensity imbalance of the two output beams from a Sagnac loop. Sub-100-fs timing jitter between the extracted 2-GHz rf signal and the 100-MHz optical pulse train from a mod...
متن کاملBalanced optical-microwave phase detectors for optoelectronic phase-locked loops.
A balanced optical-microwave phase detector for the extraction of low-jitter, high-power, and drift-free microwave signals from optical pulse trains is presented. The phase detection is based on electro-optic sampling with a differentially biased Sagnac loop. Because the timing information is transferred in the optical domain, the regenerated microwave signal is robust against drifts and photod...
متن کاملUltrashort-pulse measurement using noninstantaneous nonlinearities: Raman effects in frequency-resolved optical gating.
Ultrashort-pulse-characterization techniques generally require instantaneously responding media. We show that this is not the case for frequency-resolved optical gating (FROG). We include, as an example, the noninstantaneous Raman response of fused silica, which can cause errors in the retrieved pulse width of as much as 8% for a 25-fs pulse in polarization-gate FROG. We present a modified puls...
متن کاملOptical Opacity of Laser Induced Plasma in Distilled Water with NaCl and TiO2 Nanoparticles Impurities
In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. The plasma was induced by a 1064 nm Nd:YAG laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (I) a solution (highly diluted salt water as a conductor) and (II) a colloidal (TiO2 in colloidal nanoparticle form as a dielectric...
