Microwave pumped excimer lasers
Conference on Lasers and Electro-Optics, 1981 Microwave excitation is a simple practical method of pumping high-pressure rare-gas-halide laser systems which avoids the discharge instabilities of typical avalanche discharges. Thus long pulse high-repetition rate operation is possible. In addition, the device can be easily constructed with high-vacuum halogen compatible materials and is free from ...

InfoMat, EarlyView.Single‐domain Si‐doped β‐Ga2O3 thin films grown on off‐axis sapphire eliminate domain boundaries, improving transport and photogating. Gate‐pulse modulation suppresses persistent photoconductivity, yielding ultrafast response and high detectivity. Integrated into a 24 × 24 array, the devices enable high frame rate DUV imaging and energy‐efficient ...

Macromolecular Reaction Engineering, EarlyView.The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

Small, EarlyView.Dual circularly polarized luminescence (CPL) is demonstrated in pioneering metal‐free organic nanoparticles (ONPs) from a brominated trityl radical derivative. CPL activity in the Vis or NIR regions in aqueous environments is achieved by tayloring the content of radical enantiomers in ONPs, thanks to the generation of intrinsically chiral excimers ...

Non-Liouvillean ion injection via resonantly enhanced two-photon ionization
Physical Review Special Topics. Accelerators and Beams, 2004 The charge-exchange method is now one of the main techniques for ion injection into accelerators and storage rings. The disadvantages of conventional methods, based on the atom or ion stripping in a material target, are emittance growth, energy ...
