    Fluorescence studies of electron-beam pumped POPOP dye vapor (1976)
    Springer

    Notes: Abstract Fluorescence studies on electron-beam excited mixtures of POPOP dye vapor and various buffer gases are reported. Xenon has been found to be a promising candidate as a buffer gas for efficient energy deposition of the electron-beam and energy transfer to the POPOP dye vapor. These experiments may be an important step towards realization of an electrically excited dye vapor laser.

    Order transition at the threshold for self-excited laser pulses (1976)
    Springer

    Notes: Abstract The laser-light field is shown to undergo a discontinuous order transition at the threshold for mode-locked pulses, accompanied by critical fluctuations below the transition point. These observations confirm theoretical predictions from the laser equations for a simplified model when incoherent interaction is included.

    Electron energy loss spectra of dye vapors (1978)

    Notes: Abstract Electron energy loss studies of POPOP andp-terphenyl in the vapor phase at an incident electron energy of 25 eV have been performed. The spectra covering an energy loss between 0 and 9 eV revealed a considerable initial triplet population under electron impact excitation. The implications for electron-beam pumped vapor phase dye lasers are discussed.

    Efficient spectral narrowing and tuning of a cw dye laser with a low-loss diffraction grating (1978)
    Springer
    Applied physics 16 (1978), S. 297-301 
    Details

    Notes: Abstract A grating-tuned cw dye laser with an emission bandwidth of less than 1 GHz and output power in excess of 400 mW has been constructed. This was accomplished using a newly developed holographic grating with sinusoidal groove profile, which resulted in an enhanced spectral efficiency up to 94%. The low losses and the broad spectral working range (more than 1000 Å) which can be easily covered by simple rotation make these gratings an attractive single-stage tuning element for low-gain cw lasers.

    Threshold singularities of optically pumped dye lasers (1978)

    Notes: Abstract A complete theoretical model for optically pumped dye lasers is studied using the rate equation approach which includes excited singlet and triplet state absorption effects. Closed-form solutions under steady-state conditions reveal a novel nonlinear threshold phenomenon: partial reabsorption of the excited laser light can lead to a discontinuous onset of laser oscillation above laser threshold. Theoretical and experimental results for a transversely and longitudinally pumped rhodamine 6G laser are presented in terms of softmode and hardmode behavior at threshold.

    Feedback controlled self-excitation of optical pulses in a CW dye ring laser (1978)
    Springer

    Notes: Abstract Feedback controlled self-excitation of optical pulses of nanosecond duration has been observed to occur rather reliably in a CW dye ring laser, oscillating in a traveling mode. These observations are described analytically by means of a direct time domain approach. It is shown that a steady-state Gaussian pulse whose time duration determined from the self consistency condition in terms of system characteristics describes accurately the observed pulse behaviors.

    Notes: Abstract Excitation processes of selected dye vapor-rare gas mixtures pumped by an electron beam have been studied. These experiments revealed the importance of effective collisional electron energy transfer pumping via a dense rare gas rather than a radiative energy transfer from an excimer laser gas mixture to achieve population inversion in an organic dye vapor.
