    Simultaneous oscillation on UV and IR transitions of the copper ion laser (1991)

    Notes: Abstract Simultaneous oscillation of UV (248–270 nm) and IR lines (773–785 nm) in the copper ion laser with helical hollow cathode has been observed using high reflectivity combination mirrors. The output power characteristics of these laser lines are measured as functions of the discharge current and fill-gas pressure. A total laser power of about 100 mW with equal UV and IR contributions was obtained.

    Infrared recombination lasers pumped by low energy Nd: YAG and excimer lasers (1992)

    Notes: Abstract 24 infrared laser lines on atomic and ionic transitions have been observed in recombining plasmas by vaporizing and ionizing Cd, Pb, Sn, Zn, and Mg with low energy Nd:YAG or excimer pump-lasers. For operation and optimization of the recombination lasers separated plasma spots and a plasma confinement have been used. The operation of shorter wavelength systems by isoelectronic scaling is discussed.

    Ultra-violet excited laser emission in Na2 (1982)
    Springer
    Applied physics 29 (1982), S. 195-200 
    Details
    ISSN: 1432-0649
    Keywords: 42.55 ; 35

    Topics: Physics
    Notes: Abstract Laser emission at different wavelengths in the range of 903–914 nm and around 2.5 μm has been observed upon excitation of Na2 by uv radiation from an excimer laser at 351 nm and an excimer pumped dye laser in this wavelength range. The emission is attributed to a cascade emission $$C^1 \Pi _u \to 2^1 \sum _g^ + $$ followed by $$2^1 \sum _g^ + \to A^1 \sum _u^ + $$ . In addition, coupled with the laser emission around 910 nm, broad-band fluorescence peaking around 855.5 nm is observed which, eventually, may be the first observation of the $$b^3 \sum _g^ + \to x^3 \sum _u^ + $$ bound-free transition in Na2.

    Continuous laser emission from sodium atoms by collision assisted two-step excitation (1985)
    Springer
    Applied physics 37 (1985), S. 137-140 
    Details
    ISSN: 1432-0649
    Keywords: 42.55 ; 34

    Topics: Physics
    Notes: Abstract Continuous laser oscillation on different lines in the spectral range of 1.85 to 3.41 μm, corresponding to transitions between higher lying atomic sodium levels, has been obtained by optical excitation of sodium vapor with Rhodamine 6G dye-laser radiation, tuned either around the 3p−4d resonance (∼ 568 nm) or the 3p−5s resonance (∼ 615 nm). The pump mechanism consists of an atomic two-step excitation as well as an excitation of diatomic sodium molecules and subsequent molecular-atomic collisional energy transfer. Laser operation with low threshold pump power (〈10 mW) and large pump laser detuning (500 GHz) has been observed.

    Notes: Abstract First cw laser oscillation with thresholds below 1 mW was observed for various B1Пu → X1 ∑ g + transitions of diatomic molecular sodium excited by different argon laser lines in the range of 454–488 nm. For pump powers of 0.5 W output powers up to 3 mW and single-pass gain up to 0.1 cm−1 were obtained. Some properties of the heat pipe laser system are discussed.
