Cavity-Enhanced Room-Temperature Broadband Raman Memory.

Physical review letters

Saunders DJ, Munns JH, Champion TF, Qiu C, Kaczmarek KT, Poem E, Ledingham PM, Walmsley IA, Nunn J.
PMID: 26991164
Phys Rev Lett. 2016 Mar 04;116(9):090501. doi: 10.1103/PhysRevLett.116.090501. Epub 2016 Mar 03.

Broadband quantum memories hold great promise as multiplexing elements in future photonic quantum information protocols. Alkali-vapor Raman memories combine high-bandwidth storage, on-demand readout, and operation at room temperature without collisional fluorescence noise. However, previous implementations have required large control...

Experimental study of proton emission from 60-fs, 200-mJ high-repetition-rate tabletop-laser pulses interacting with solid targets.

Physical review. E, Statistical, nonlinear, and soft matter physics

Measurements of proton emission have been made from a variety of solid targets irradiated by a 60-fs, 200-mJ, 7 x 10(18)-W cm(-2) laser system operating at 2 Hz. Optimum target conditions were found in terms of target material and...

Rapid Commun Mass Spectrom. 1999;13(14):1366-73. doi: 10.1002/(SICI)1097-0231(19990730)13:14<1366::AID-RCM644>3.0.CO;2-3.

With the development of high intensity femtosecond lasers, the ionisation and dissociation dynamics of molecules has become an area of considerable interest. Using the technique of femtosecond laser mass spectrometry (FLMS), the molecules carbon disulphide, pyrimidine, toluene, cyclohexanone and...

The interaction of 1-iodopropane, 2-iodopropane, 1-iodobutane, 2-iodobutane, and 1-iodopentane with (5 x 10(13-)5 x 10(15) W/cm2) femtosecond laser fields is studied by means of a time-of-flight mass spectrometer. It is found that multiphoton ionization (MPI) and field ionization (FI)...

Broad energy spectrum of laser-accelerated protons for spallation-related physics.

Physical review letters

Phys Rev Lett. 2005 Mar 04;94(8):084801. doi: 10.1103/PhysRevLett.94.084801. Epub 2005 Mar 04.

A beam of MeV protons, accelerated by ultraintense laser-pulse interactions with a thin target foil, is used to investigate nuclear reactions of interest for spallation physics. The laser-generated proton beam is shown (protons were measured) to have a broad...
