The results of an experimental investigation of an optically pumped vibrational laser in HCl are reported. Two different excitation sources were used: a Nd:yttrium–aluminum–garnet laser pumped optical parametric oscillator and a Raman shifted ale

Our pulsed fast oxygen atom source has been used extensively over the last 9 yr to investigate the effects of ambient oxygen atoms that impact materials placed in LEO. During this period, we have irradiated over 2000 material samples with 8 km/s oxyg

This paper deals with the management of the often brief pollution incident which gives rise to a sudden emergency. There are two key aspects to pollution risk management: the identification and minimisation of potential and actual risks (pro-active m

The chemistry of electric discharge driven oxygen iodine lasers (EOIL) has long been believed to have O 2 (a 1 ug) as the sole energy carrier for excitation of the lasing state I( 2 P 1/2 ), and O( 3 P) as the primary quencher of this state. In many

Scaling of EOIL systems to higher powers requires extension of electric discharge powers into the kW range and beyond with high efficiency and singlet oxygen yield. We have previously demonstrated a high-power microwave discharge approach capable of

Generation of singlet oxygen metastables, O 2 (a 1 Δ), in an electric discharge plasma offers the potential for development of compact electric oxygen-iodine laser (EOIL) systems using a recyclable, all-gas-phase medium. The primary technical challe

We have demonstrated a high-sensitivity, room-temperature quantum-cascade (QC) laser sensor for detection of SO2 and SO3 under conditions relevant to aircraft test combustor exhaust. Two QC lasers probe infrared absorption features at 7.50 and 7.16 m

This paper discusses methods, using non-intrusive diagnostic techniques, to characterize the detailed dynamics of I* gain and O2(a1Δ) yield on a laboratory microwave-discharge flow reactor, for conditions relevant to the electrically driven COIL con
