... error is about equal to the diffraction error. If one doubles this aperture so that the diffraction error is halved, the spherical aberration error is increased 8 times, and the image is hopelessly blurred. After pondering this problem for a long time, a solution suddenly dawned on me, one fine day ...

... beams in a photorefractive medium: equations (2), (3). For simplicity and comparison with the experimental conditions discussed below we only considered the frequency degenerate ( = 0) and short Debye length (α = ξ = 0) limit. We also assumed the lack of a photogalvanic effect (E ph = 0). We used a ...

In OCSe this last vibration, v3, has a first excited state above the ground state by about 10 kT so that the Boltzmann factor allows only a very small population of this level. For this reason we have not observed any absorption due to the m ...
