The ultrahigh-peak-power laser: present and future
(Springer-Verlag, 1997-08)
to 10 20 -W/cm 2 range. With some refinements and with superior energy storage materials, even higher peak power in the petawatt range should be possible from tabletop systems. In this paper we show the ultimate achievable ...
The largest set partitioned by a subfamily of a cover
(Elsevier, 1990-07)
Define [lambda](n) to be the largest integer such that for each set A of size n and cover J of A, there exist B [subset of or equal to] A and G [subset of or equal to] J such that |B| = [lambda](n) and the restriction of ...
Reduction of multi-photon ionization in dielectrics due to collisions
(Springer-Verlag, 1996-12)
The collisional effect due to the multi-photon ionization process in dielectric material has been studied. We found that the breakdown threshold of fused silica is the same for both linearly and circularly polarized light ...
Wavelength selective detection using excitonic resonances in GaAs/AlGaAs P-I-(MQW)-N structures
(Elsevier, 1990)
The quantum confined Stark effect causes a strong wavelength and voltage dependence of photocurrent near excitonic resonances which is used to study the wavelength selectivity of p-i(MQW)-n photodiode. For a parallel input ...
Efficient convexity and domination algorithms for fine- and medium-grain hypercube computers
(Springer-Verlag; Springer-Verlag New York Inc., 1992-12)
This paper gives hypercube algorithms for some simple problems involving geometric properties of sets of points. The properties considered emphasize aspects of convexity and domination. Efficient algorithms are given for ...
Enhanced and quenched Raman scattering by interface phonons in semiconductor superlattices: What are the defects?
(Elsevier, 1988)
We report on the magnetic field and power density dependences of resonant Raman scattering by interface phonons in GaAs---AlxGa1-xAs superlattices. Strong photoexcitation leads to quenching of the nominally forbidden (and ...
