    Theory of synchronously pumped dye lasers (1983)
    Springer
    Applied physics 30 (1983), S. 135-142 
    Details
    ISSN: 1432-0649
    Keywords: 42.55 ; 42.60 ; 42.80

    Topics: Physics
    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.

    Photoionization detection of stimulated Raman scattering on electron transitions of Na in an atomic beam (1983)
    Springer
    Applied physics 31 (1983), S. 135-137 
    Details
    ISSN: 1432-0649
    Keywords: 32 ; 42.65

    Topics: Physics
    Notes: Abstract Stimulated Raman scattering has been experimentally studied by using the process of two-step ionization of a Na atomic beam. A dip that is due to a resonance at a combination frequency corresponding to the forbidden 3S–4S transition of a Na atom was observed in the signal of nonresonant photoionization when two laser frequencies λ1=284.5 nm and λ2=1.06 μm were overlapped.

    A discussion of the problem of determining multiple lifetimes from picosecond absorption recovery data as encountered in two carbocyanine dyes (1983)
    Springer
    Applied physics 31 (1983), S. 235-247

    Topics: Physics
    Notes: Abstract Absorption recovery kinetics data on the picosecond time-scale of a high signalto-noise ratio can be obtained by using continuously operating synchronously modelocked dye lasers. We show that such data make it possible to determine multiple exponential decays with small differences in rate constants. We also show that an absolute prerequisite to accomplish this is that the measurements are performed at a number of different wavelengths, and that the decays are monitored in a time interval corresponding to several lifetimes. These considerations are demonstrated by measurements on two carbocyanine dyes, DQOCI and pinacyanol, respectively.

    Color signal correlation detection by matched spatial filtering (1983)

    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.

    Waveform of the amplitude modulated laser light by means of a mechanical chopper (1983)
    Springer

    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.

    Dressed-atom approach for probe spectroscopy in Doppler-broadened three-level systems with standing-wave saturator (1983)
    Springer
    Applied physics 31 (1983), S. 115-129 
    Details
    ISSN: 1432-0649

    Topics: Physics
    Notes: Abstract The three-level probe spectroscopy of Doppler-broadened transitions in the presence of a standing wave pump laser is investigated through a diagrammatic method. A probe-response diagram is defined where the resonance positions versus the probe laser frequency and absorber velocity are plotted. The dressed atom description provides a convenient method for deriving the probe response diagram and calculating the position of the Doppler-free structures on the absorption spectrum, including the ac Stark shifts. We have interpreted probe spectra on the basis of the probe response diagram, presenting new features and giving a detailed physical interpretation of all the coherent effects appearing in the spectra. Population effects are not included in the dressed system analysis and are calculated on the basis of a semiclassical treatment, but the probe response diagram provides a complete interpretation of the involved phenomena.

    Notes: Abstract A split detector is used in a scanning optical microscope to produce high-quality differential amplitude contrast images. A slight lateral offset in the detector position is shown to introduce information about object height variations to the image. These results are compared with images obtained by electrical differentiation.

    Coherence requirement for partially coherent correlation detection (1983)
    Springer

    Topics: Physics
    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.
