    Notes: Abstract An analysis of cw synchronously pumped dye lasers is presented. Under the assumption that the cavity (tuning element) bandwidth is much wider than the bandwidth of the transform limited pulses generated, the pulse forming dynamics is rigorously treated. It is shown that for a finite mismatch between the lengths of the dye and the pump lasers, a steady-state pulse develops in the dye laser cavity with a conserved pulseshape. The characteristics (energy, shape, peak power, duration) of these pulses of ultimate width are quantitatively determined as a function of cavity mismatch. An analytical solution for the pulse envelope is determined, which yieldsI(t)∝Sech2(t/t p ) to a good approximation.

    Notes: Abstract A polychromatic correlation detection technique by complex spatial filtering is presented. This technique utilizes a diffraction grating and three co-lineared (red, green, and blue) coherent sources. The technique of complex spatial filter synthesis for the polychromatic corelation detection is demonstrated. This technique offers true color correlation detection which is very suitable for color signal recognition and identification. The correlation diffraction efficiency with this technique is generally higher than that of the wavelength-multiplexed technique. Several interesting experimental demonstrations of this color signal correlation detection scheme are provided. Finally we note that this color signal detection technique is a simple and versatile processing technique which has broad range of applications of complex color signal detection, recognition and identification.

    Notes: Abstract The model which reproduces accurately and conveniently the waveform of the amplitude modulated cw laser light in the TEM00 mode by a mechanical chopper is developed. It is found that its predictions are in good agreement with the strict, completely accurate but rather lengthy and inconvenient treatment and with the experiment. The criterion for the efficient amplitude modulation of the laser light by a mechanical chopper is formulated.

    Coherence requirement for partially coherent correlation detection (1983)

    Notes: Abstract The coherence requirement for correlation detection is determined using the theory of partially coherent light. It is shown that the requirement for temporal coherence strongly dependes on the spatial frequency and the spatial extension of the target (i.e., space bandwidth product). However, the spatial coherence requirement depends only on the extension of the target. Some numerical results are also presented.

    Ambartsumian's principle of invariance and the reflection of radio waves from plane inhomogeneous slabs (1983)

    Notes: Abstract Using Ambartsumian's principle of invariance we investigate for radio waves the reflection coefficient of a plane inhomogeneous slab. We find that the reflection coefficient, as a function of slab thickness, satisfies the Riccati equation. From this equation we deduce a geometric theorem on the upper and lower bounds of the reflection coefficient. We illustrate the theorem by applying it to several special cases.

    Complete and reversible absorption of radiation (1983)

    Notes: Abstract Kirchhoff's law has caused confusion in the discussion about the theoretical maximum work from radiation because it permits only infinitesimal or irreversible absorption. With the aid of an optical circulator, non-Kirchhoff behaviour is possible in principle which permits at the same time complete and reversible radiation absorption. The key to overcome Kirchhoff's law seems to be the magnetic field, a condition explicitly excluded by Kirchhoff. The work extracted in complete reversible conversion of radiation is calculated. The irreversibilities connected with the emission process are discussed.

    Diffraction efficiencies of evanescent-wave holograms (1983)

    Notes: Abstract In contrast to previous models diffraction efficiencies of evanescent-wave holograms are calculated within the framework of a slab model that takes into account the finite thickness of the recording medium. This modification leads to characteristic diffraction efficiency oscillations with respect to reconstruction angle and medium thickness as well. One obtains higher diffraction efficiency maxima and pseudo-optical tunnelling. The analysis covers TE-polarized fields.

    Modulation of radiation in nonstationary resonant media (1983)

    Notes: Abstract We study the propagation of radiation in a gas, the resonant frequency of which changes with time when affected by external electric and magnetic fields. It is shown that for an harmonic change of the resonant frequency under appreciable energy exchange between electromagnetic field and medium, deep amplitude modulation of radiation may be achieved. The analytical expressions obtained for a field in a gas allow rather accurate calculation of the space-time structure of the radiation penetrated through the medium layer. The numerical calculations are compared with the known experiment [4], good agreement is obtained. The transformation of radiation between dispersive branches with adiabatic stepwise variation of the resonant frequency has been also studied. Branch-tobranch transformation is investigated and the adiabatic invariant is found to be the total number of the high and low frequency radiation quanta corresponding to two dispersive branches.

    Notes: Abstract We have measured the changes in the polarization state of a monochromatic (λ=514.5 nm) light beam on reflection at normal incidence by a multilayer dielectric mirror placed in a time-modulated magnetic field. The dominant effect is a Faraday rotationΦ≃3.7×10−10 rad/G. The sensitivity (around 40Hz) obtained is $$ \simeq 6 \times 10^{ - 9} {\text{ rad/}}\sqrt {{\text{Hz}}} $$ which is dominated by the shot-noise limit (100 mW of light power).

The change of refractive index and titanium concentration are related by a power law, the exponents being different for the extraordinary and the ordinary beam.

    Measuring the Magnetooptic Kerr effect by diffraction (1983)

    Notes: Abstract A method is presented to measure the Magnetooptic Kerr Effect (MOKE) by diffraction. This is accomplished by giving the magnetized surface a magnetization distribution which functions like a linear diffraction grating. It is shown that the first and higher orders of the light diffracted by such a grating are produced by MOKE whereas the zero order approximately represents the reflectivity of the surface (given by the Fresnel formulae assuming zero magnetization). The procedure used here to form a grating is restricted to thin soft magnetic films, and has been demonstrated on evaporated Fe-Ni films. It uses the magnetic field of a pulse-driven meandered stripe-conductor placed in close contact with the film in the presence of a homogeneous external magnetic field. Experimentally determined Kerr intensities were compared with those measured by ellipsometric methods. Good agreement was found in the case of films with uniaxial anisotropy. For films with no anisotropy, the relative dependence of Kerr intensity vs wavelength, polarisation and angle of incidence could be derived.
