Picosecond ionization dynamics in femtosecond filaments at high pressures [PDF]
, 2017 We investigate the plasma dynamics inside a femtosecond-pulse-induced filament generated in an argon gas for a wide range of pressures up to 60 bar. At higher pressures, we observe ionization immediately following a pulse, with up to a threefold increase

Ionizing and Non-ionizing Radiation [PDF]
, 2017 This chapter describes ionizing radiation and non-ionizing radiation, ways to measure it in the environment, describes the potential health effects from chronic and acute exposures as well as a discussion addressing pregnancy concerns. Background radiation from both sources are described in relation to occupational or public exposure limits and how ...

Intensity-Resolved Above Threshold Ionization of Xenon with Short Laser Pulses [PDF]
, 2014 We present intensity-resolved above threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser pulses of 58 fs and central wavelength of 800 nm from a chirped-pulse ...

Effect of impact ionization in the InGaAs absorber on excess noise of avalanche photodiodes [PDF]
, 2005 The effects of impact ionization in the InGaAs absorption layer on the multiplication, excess noise and breakdown voltage are modeled for avalanche photodiodes (APDs), both with InP and with InAlAs multiplication regions.

Laboratory Photo-chemistry of PAHs: Ionization versus Fragmentation [PDF]
, 2015 Interstellar polycyclic aromatic hydrocarbons (PAHs) are expected to be strongly processed by vacuum ultraviolet photons. Here, we report experimental studies on the ionization and fragmentation of coronene (C24H12), ovalene (C32H14) and hexa-peri ...
