Optimal Control of Multiphoton Ionization Processes in I2 Molecules with Time-Dependent Polarization Pulses
Optimal control Genetic algorithm Time-dependent polarization pulse
2009/6/15
We have developed a closed-loop pulse shaping system with a spatial light modulator, where even a time-dependent polarization pulse can be generated and controlled. An outline of the developed pulse s...
Red and Green Distributed-Feedback LiF Color Center Lasers Fabricated by Interference of Femtosecond Laser Pulses
Color centers Distributed-feedback laser Femtosecond laser
2009/6/1
Sub-micron periodic gratings inside bulk lithium fluoride (LiF) are holographically fabricated by interference with the second harmonic (390 nm) of a mode-locked Ti:sapphire oscillator-amplifier laser...
Photorefractive Amplification of Few-cycle Laser Pulses
Ultrashort pulse lasers Multi-photon interference Photorefractive effect
2009/6/1
Few-cycle pulse amplification by two-photon arranged photorefractive device has been demonstrated. An extraction efficiency of 27 % has been achieved with a gain-bandwidth of 32 THz.
Influence of Asymmetric Pulses in Spread Spectrum Systems
Asymmetric pulses Spread spectrum systems M-sequences Autocorrelation function
2010/12/8
This paper examines the impact of asymmetric pulses in NRZ waveforms generated by maximum-length sequences and used in spread spectrum systems. The data asymmetry phenomenon is produced by differentia...
The Influence of Electrical Pulses on Thick Film (Du Pont 1421 Birox) Resistors
Electrical Pulses Thick Film (Du Pont 1421 Birox) Resistors
2010/12/28
This paper presents data on the effect of electric pulses on thick film resistors made using Du Pont 1421 Birox resistor pastes.
Resistance changes during the application of the electric pulses were ...
