    CW and quasi-CW diode-laser-pumped Nd:SSGM (1995)
    Springer
    Applied physics 60 (1995), S. 67-69 
    Details
    ISSN: 1432-0649
    Keywords: 42.55.Rz ; 42.60.By

    Topics: Physics
    Notes: Abstract Fiber-coupled laser diodes were used to pump a Nd-doped SGGM slab (Nd: 4at.%) in the Continous Wave (CW) and Quasi-CW (Q-CW) modes of operation. The optical-to-optical and slope efficiencies were determined in both cases.

    Efficiency of diode-pumped 1.35µm laser from Nd:KGW (1996)
    Springer

    Topics: Physics
    Notes: Abstract A set of quasi-Continuous-Wave (CW) diode lasers has been used to pump Nd:KGW and to generate 1.35µm laser radiation at room temperature. The optical-to-optical and slope efficiencies have been measured and compared with those of Nd:YAG at identical experimental conditions.

    High-efficiency continuous-wave diode-pumped Tm:Ho:LuAG laser at 2.1 μm (1996)
    Springer
    Applied physics 62 (1996), S. 109-111

    Topics: Physics
    Notes: Abstract Continuous Wave (CW) laser action has been observed from a Ho:Tm:LuAG rod at 2.1 μm pumped by a diode laser at 785 nm in the temperature range of 77–200 K. The maximum power observed was 1.38 W at an incident power of 4 W at a crystal temperature of 77 K. The optical-to-optical conversion efficiency was observed to be 35.6% at a threshold power of 0.2 W with a 95% output coupling mirror.

    Notes: Slime-covered rocks and samples of process waters from two trickling filters for treatment of municipal wastes were brought to the laboratory for probing with microelectrodes to determine dissolved oxygen (DO). Slime thickness was 0.4-1.5 mm. Flow rate of medium over the slime had a minor effect on slime respiration, but pH 5 or below was strongly inhibitory. Increasing temperature showed lower oxygen concentration throughout a slime, although 27°C had results little different from those at 22°C. Medium concentration had a profound effect on oxygen concentration profiles, and either oxygen-limited or substrate limited respiration could be demonstrated. Illumination of slimes from the top of the trickling filter developed oxygen supersaturation because oxygen from photosynthesis could not diffuse away rapidly.

    Substrate utilization kinetic model for biological treatment process (1980)

    Notes: The applicability of Contois' kinetic equation to aerobic and anaerobic treatments of organic wastes is investigated. A refractory coefficient to account for the nonbiodegradable portion of the organic substrates in the digester is incorporated into the kinetic equation. The kinetic equation is applied to the data for aerobic digestions of organic substrates and for anaerobic treatment of dairy wastes. They all show a very good fit of the kinetic equation to the data. Furthermore, the kinetic parameters and the refractory coefficients are shown to be independent of influent organic substrate concentration. This study confirms previous reports that the effluent quality of biological treatment systems for organic wastes depends on influent organic waste concentration. The effect of temperature on the kinetic parameters and the refractory coefficient for anaerobic treatment of sewage sludge are studied. It shows that the kinetic parameters vary with temperature, while the refractory coefficient remains fairly constant. Equations to predict biodegradable treatment efficiency and volumetric substrate utilization rate are also briefly discussed.
