    Notes: Abstract A dielectric laser cavity of 1 cm length has been optimized for high gain (7 cm−1) operation which is achieved in XeF doped Ar crystals. Mode structures on the C-A spectral distribution around 540 nm and far field transverse mode patterns are reported. Photchemical gain burning is observed in the spectral mode structures. The dependence of the laser threshold on pump energy, pumped length and on cavity losses is studied. XeF densities of 7×1017 cm−3 and distributed losses of 1.2 cm−1 are derived. The measured quantum efficiency of 14% and the saturation behaviour are consistently described. Losses by transient aborption and two photon absorption are discussed.

    Laserspectroscopic investigations of the lithium-D-lines in magnetic fields (1990)
    Springer
    The European physical journal 16 (1990), S. 41-47

    Notes: Abstract Laser-atomic-beam investigations of the lithiumD 1- andD 2-line in magnetic fields were performed using cw-laser excitation and fluorescence detection. For both isotopes6Li and7Li, the hyperfine splittings of the ground level 22 S 1/2 and the upper level of theD 1-line, 22 P 1/2, as well as the isotopic shifts of theD 1- and theD 2-line were determined from the registrations without field. In magnetic fields, Zeeman- and Paschen-Back-effects of the lines were studied. Using the Zeeman pattern of theD 1-line for a calibration of the field strength, values for the hyperfine constantsA andB of the 22 P 3/2-level of7Li could be derived from the Zeeman pattern of theD 2-line.
