    Photophysical properties and laser performance of photostable UV laser dyes (1988)
    Springer
    Applied physics 45 (1988), S. 279-284

    ISSN: 1432-0649
    Keywords: 07.65 ; 33 ; 42.55 ; 82.50

    Topics: Physics
    Notes: Abstract The photophysical properties such as singlet absorption and fluorescence spectra, the fluorescence quantum yield and fluorescence decay time as well as the laser performance data such as the tuning range, the conversion efficiency, and the photochemical stability of 12 sterically hinderedp-quaterphenyls have been measured in ethanol and/or dioxane at room temperature. The sterically hinderedp-quaterphenyls exhibit shorter laser dye emissions in the 330–380 nm range than the parent compoundp-quaterphenyl. The conversion efficiencies of the sterically hinderedp-quaterphenyls range between 1 and 21%. The photochemical stability of the sterically hinderedp-quaterphenyls is by a factor of 10 to 20 better in dioxane than in ethanol. 2-Methyl-5-tert. butyl-p-quaterphenyl and 2,5,2‴,5‴-tetramethyl-p-quaterphenyl are among the most stable UV laser dyes known today.

    A continuously tunable GaAs diode laser with an external resonator (1989)
    Springer
    Applied physics 49 (1989), S. 29-32 
    Details
    ISSN: 1432-0649
    Keywords: 42.55 ; 42.60B
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Design and characteristics of an “external cavity single mode GaAs diode laser” are described which allow continuous wavelength tuning over 50 GHz without mode hops. Tuning is achieved by synchronous tilting of both a thin solid etalon and a Brewster plate inside the laser resonator. Stabilizing the laser frequency to an external Fabry-Perot interferometer yields a frequency stability of ≦1 MHz at output powers up to 20 m W.

    New submillimetre laser lines from CH3OD and CD3OD (1985)
    Springer
    Applied physics 37 (1985), S. 209-211 
    Details
    ISSN: 1432-0649
    Keywords: 42.55
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Thirteen new submillimetre emission lines have been observed when pumping CH3OD using isotopic CO2 lasers, and fourteen when pumping CD3OD. Three isotopic CO2 lasers were used12C16O2,12C18O2, and13C16O2. The new lines were observed in a Fabry-Perot resonator. The wavelength ranges observed were from 55 to 320 μm for CH3OD and from 66 to 531 μm for CD3OD. The polarisation of the submillimetre laser lines relative to the CO2 pump line has also been determined.

    Simple single-frequency He-Ne laser (1986)
    Springer
    Applied physics 40 (1986), S. 153-155

    ISSN: 1432-0649
    Keywords: 42.60 ; 42.55

    Topics: Physics
    Notes: Abstract For a (0.5–0.6)m long He−Ne laser tube, single longitudinal mode 632.8 nm generation is obtained, using a higher gas-mixture pressure and application of an axial magnetic field. An efficient and very simple mode selection is obtained by gas-mixture pressure increase only. A multimode power to single-mode power conversion coefficientk=0.75 is obtained by increasing the tube pressure. A further increase tok=0.85 is possible with optimum magnetic field and gas pressure.

    On the opto-voltaic measurements in CO and CO2 lasers (1985)
    Springer
    Applied physics 36 (1985), S. 149-153

    ISSN: 1432-0649
    Keywords: 42.55 ; 42.60 ; 42.80
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We observed and compared the opto-voltaic signals in CO and CO2 lasers. The signals are obtained capacitively from the water cooling jacket as a low voltage source not influencing the current circuit. We observed from measurement that the output power and the so-called optovoltaic input power have a distinct relationship depending on laser current and cavity parameters. It will be shown that opto-voltaic detection is a very sensitive method especially for CO lasers.

    Notes: Abstract Rhodamine 6G-Cresyl violet dye mixtures are synchronously pumped to obtain double mode-locking. Subpicosecond pulses are obtained at two wavelengths in an experimental setup that is easy to implement into existing conventional synchronously pumped systems. In addition, the excitation mechanisms of the secondary dye are discussed and evidence for resonant energy transfer is presented.

    An oscillator-amplifier distributed feedback dye laser system, pumped by a single TEA N2 laser (1985)
    Springer
    Applied physics 37 (1985), S. 35-39 
    Details
    ISSN: 1432-0649
    Keywords: 42.55
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract In this paper we describe a simple and inexpensive Distributed Feedback Dye Laser (DFDL) system for picosecond pulse generation. This system consists of an oscillator-amplifier DFDL, either in the grating or in the prism configuration: both stages are pumped by a single TEA nitrogen laser with improved beam quality. Single pulses having duration of 26 ps are obtained at a frequency up to 100Hz; the overall pulse-to-pulse stability is, at the maximum frequency, of about 25%. This system is particularly well-suited for time-resolved fluorescence microscopy studies where short tunable laser pulses of low energy are required.

    Notes: Abstract In this letter paper we analyse the effect of electron-beam qualities (namely, energy spread and emittances) on both spontaneous emission and gain of an Optical Klystron (OK). We use the relationship between average current and normalized emittances, typical of the accelerating machines without radiative damping, to evaluate the optimum operating parameters.
