    Tunable infrared generation using the 6s−5d Raman transition in caesium vapour (1980)
    Springer

    Notizen: Abstract Coherent infrared radiation tunable between 1.6 and 3.2 μm was generated with a pulsed dye laser by 6s−5d 5/2 stimulated electronic Raman scattering in caesium vapour. We describe a technique using thermal dissociation to reduce the density of caesium dimers in a heat-pipe oven, which produced a factor of 7 reduction in Raman threshold. The threshold displayed a marked dependence on pump bandwidth.

    Wide-range line-tunable oscillation of an optically pumped NH3 laser (1980)
    Springer
    Applied physics 21 (1980), S. 237-240 
    Details
    ISSN: 1432-0630

    Thema: Maschinenbau , Physik
    Notizen: Abstract Selective single-line oscillation has been obtained from an NH3 laser in the range from 11 to 13 μm. Pumping of high pressure NH3−He mixture with theR(30) line of a TEA-CO2 laser made it possible to tune on more than 30 lines with the aid of a grating. However, such line tunable oscillation was not observed when theR(16) line was used for pumping. Reasons for this difference are discussed.

    Simplification of the helical TE N2 laser (1980)
    Springer
    Applied physics 21 (1980), S. 319-321 
    Details
    ISSN: 1432-0630
    Schlagwort(e): 42.55 ; 42.60
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau , Physik
    Notizen: Abstract We report the observation that the helical TE N2 laser can effectively be simplified by giving up the use of decoupling elements as well as by abolishing the segmentation of the electrode structure. Although, as a consequence of this simplification, the operating pressure range was slightly decreased, the output power could be improved by roughly 30%, a result which is attributed to the new electrode geometry exhibiting lower inductance and lower damping losses.

    Transient behaviour of pulsed dye lasers (1980)
    Springer
    Applied physics 21 (1980), S. 353-359 
    Details
    ISSN: 1432-0630
    Schlagwort(e): 42.10 ; 42.60 ; 42.80
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau , Physik
    Notizen: Abstract Some aspects of the transient behaviour of pulsed dye lasers are investigated both theoretically and experimentally. Relaxation oscillations induced in the output from a dye cell by an external reflector have been observed and explained, using a rate equation approximation to the physical situation in the dye cell. These oscillations are shown to play an important part in the generation of short laser pulses from long cavity dye lasers. Finally, it is proposed that 10 ps pulses can be obtained from conventional dye lasers pumped by 100 ps pulses from a high-pressure nitrogen laser.

    Periodic pulse solutions of a laser consisting of a pair of amplifiers mode locked by a fast saturable absorber (1980)
    Springer
    Applied physics 22 (1980), S. 213-218

    ISSN: 1432-0630

    Thema: Maschinenbau , Physik
    Notizen: Abstract We present periodic solutions, which are described in terms of Jacobian elliptic functions, for the steady state pulses from a laser system consisting of a pair of amplifiers of unequal relaxation time mode locked by a “fast” saturable absorber. The pulsewidth and the average power in the pulse are expressed interms of the system parameters through two different approaches, where detailed plots are given for one of the approaches. Summary of the characters to be possessed by the amplifier pair to ensure the reliable production of shortest possible pulses is given.

    Notizen: Abstract The development of excimers and excimer lasers are reviewed. The excimers of the noble gases (Xe 2 * , Kr 2 * , Ar 2 * ) and of the noble gas halides (e.g. KrF, XeCl) which, respectively, radiate in the vacuum ultra-violet and ultra-violet regions of the spectrum are described in terms of their structure, spectroscopy and formation kinetics and the methods of pumping, operational characteristics and applications of the lasers are discussed.

    Coherence time measurement of picosecond pulses by a light-induced grating method (1980)
    Springer
    Applied physics 21 (1980), S. 215-219

    Thema: Maschinenbau , Physik
    Notizen: Abstract The temporal coherence function |Γ(τ)| of picosecond pulses from a Nd: YAG laser has been measured by diffraction at a transient grating. The coherence timet c =7 ps is small compared to the pulse widtht p =22 ps but is in correspondence with the spectral bandwidth Δv=12·1010 Hz. The new method for measuring the coherence function |Γ(τ)| is discussed and compared with a previous experiment.

    Solvent effects on the gain of rhodamine 6G (1980)
    Springer
    Applied physics 23 (1980), S. 253-258 
    Details
    ISSN: 1432-0630
    Schlagwort(e): 42.60 ; 78.30 ; 78.60
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau , Physik
    Notizen: Abstract The effect of solvents on the gain and the peaks of gain spectra is investigated for rhodamine 6G (R6G) under nitrogen laser pumping. The non-specific solute-solvent interaction for R6G is found to be mainly dispersive. Additional shifts produced for R6G in certain solvents are explained as due to hydrogen bonding. The gain characteristics are interpreted on the basis of the position and overlap of absorption and fluorescence spectra, the quantum yield, the absorption at the pumping wavelength and the refractive index of the solvent. For the solvents studied it is found that R6G has high gain in solvents with low refractive index and high polarity. Amongst the solvents studied the alcohols displayed the highest gain with methanol being the most suitable solvent. The lowest gain amongst the alcohols was with capryllic alcohol which gave a gain that was 69% of that obtained with methanol. Amongst all the solvents studied the lowest gain was with chloroform, being only 34% of the gain in methanol.
