Atomic excitation during recollision-free ultrafast multi-electron tunnel ionization
W. A. Bryan, S. L. Stebbings, J. McKenna +12
Modern intense ultrafast pulsed lasers generate an electric field of sufficient strength to permit tunnel ionization of the valence electrons in atoms. This process is usually trea…
Ultra-low noise microwave generation with fiber-based optical frequency comb and application to atomic fountain clock
J. Millo, M. Abgrall, M. Lours +8
We demonstrate the use of a fiber-based femtosecond laser locked onto an ultra-stable optical cavity to generate a low-noise microwave reference signal. Comparison with both a liqu…
Ultrastable lasers based on vibration insensitive cavities
J. Millo, D. V. Magalhaes, C. Mandache +7
We present two ultra-stable lasers based on two vibration insensitive cavity designs, one with vertical optical axis geometry, the other horizontal. Ultra-stable cavities are const…
Isolated vibrational wavepackets in D2+: Defining superposition conditions and wavepacket distinguishability
W. A. Bryan, J. McKenna, E. M. L. English +9
Tunnel ionization of room-temperature D in an ultrashort (12 femtosecond) near infra-red (800 nm) pump laser pulse excites a vibrational wavepacket in the D2+ ions; a rotationa…
Mapping the Evolution of Optically-Generated Rotational Wavepackets in a Room Temperature Ensemble of D
W. A. Bryan, E. M. L. English, J. McKenna +7
A coherent superposition of rotational states in D has been excited by nonresonant ultrafast (12 femtosecond) intense (2 10 Wcm) 800 nm laser pulses lead…
On the recollision-free excitation of krypton during ultrafast multi-electron tunnel ionization
W A Bryan, S L Stebbings, J McKenna +7
The probability of multiple ionization of krypton by 50 femtosecond circularly polarized laser pulses, independent of the optical focal geometry, has been obtained for the first ti…
