    Laser ablation of polymeric materials at 157 nm (1995)

    Notes: Results are presented on the ablation by 157 nm laser radiation of polytetrafluoroethylene (PTFE), polyimide, polyhydroxybutyrate (PHB), poly(methyl methacrylate) (PMMA), and poly(2-hydroxyethyl methacrylate) with 1% of ethylene glycol dimethacrylate as a crosslinking monomer. Direct photoetching of PHB and undoped PTFE is demonstrated for laser fluences ranging from 0.05 to 0.8 J/cm2. The dependence of the ablation process on the polymer structure is analyzed, and insight into the ablation mechanism is gained from an analysis of the data using Beer–Lambert's law and the kinetic model of the moving interface. Consideration of the absorbed energy density required to initiate significant ablation suggests that the photoetching mechanism is similar for all the polymers studied. © 1995 American Institute of Physics.

    The absorption of 158 nm radiation in nitric oxide (1990)
    Springer
    Applied physics 51 (1990), S. 127-131

    Topics: Physics
    Notes: Abstract We propose an optically pumped laser which would operate in the vacuum ultraviolet region of the spectrum with pulse energies in the millijoule range. The proposed laser is expected to oscillate on 8–10 transitions with wavelengths between 158 nm and 242 nm. The results of an absorption experiment and a kinetic model are used to evaluate the prospects for such a laser.

    Influence of cavity configuration on the pulse energy of a high-pressure molecular fluorine laser (1992)
    Springer
    Applied physics 55 (1992), S. 54-59

    Notes: Abstract We report an investigation of a high-pressure molecular fluorine laser operating at 158 nm. Several cavity configurations were studied, including one employing a roof prism as the high reflector. A maximum VUV pulse energy of 237 mJ, corresponding to a specific output of 3.3 J/1 was obtained when the laser was operated as a double-ended device. With single-ended operation the largest output energy was 176 mJ at a specific output of 2.5 J/1.

    Vacuum ultraviolet gain measurements in optically pumped LiYF4:Nd3+ (1997)
    Springer
    Applied physics 64 (1997), S. 293-300

    Notes: Abstract.  We present measurements of the net-induced gain on the 5d–4f transition at 186 nm in LiYF4 : Nd3+ optically pumped by radiation from a molecular fluorine laser. It is found that for LiYF4 : Nd3+, one of a series of potential continuously tunable VUV lasers, relatively strong excited-state absorption results in net-induced loss. The prospects for VUV laser operation being realised in other rare-earth-doped fluorides is discussed.

    Observation of new laser transitions and saturation effects in optically pumped NO (1992)

    Notes: Abstract We report investigations of an NO laser employing specially profiled magnetic fields of up to 3.4T, and F2 pump laser intensities as great as 20 MW cm−2. We have observed laser oscillation at 226 nm on a rotational branch of the B'-X/it(3–11) band of NO for the first time, in addition to the previously reported oscillation at 218 nm on the B'-X/it(3–10) band. We have also observed visible laser emission on a rotational branch of the B′ 2Δ-B 2 II(3–1) band of NO. Saturation of the NO laser pulse energy with pump intensity has been observed, the total NO laser pulse energy having been increased to 490 μJ. The possibility of increasing the NO laser pulse energy towards 1 mJ per transition is discussed.
