Subcycle engineering of laser filamentation in gas by harmonic seeding
P. Béjot, G. Karras, F. Billard +4
Manipulating at will the propagation dynamics of high power laser pulses is a long-standing dream whose accomplishment would lead to the control of a plethora of fascinating physic…

Harmonic generation and filamentation: when secondary radiations have primary consequences
P. Béjot, G. Karras, F. Billard +4
In this Letter, it is experimentally and theoretically shown that weak odd harmonics generated during the propagation of an infrared ultrashort ultra-intense pulse unexpectedly mod…

On the interpretation of negative birefringence observed in strong-field optical pump-probe experiments: high-order Kerr and plasma grating effects
G. Karras, P. Béjot, J. Houzet +4
The analysis of negative birefringence optically induced in major air components (Loriot et al., [1, 2]) is revisited in light of the recently reported plasma grating-induced phase…
