Simultaneous spatial and temporal focusing (SSTF) of femtosecond laser pulses gives rise to strong suppression of nonlinear self-focusing during the propagation of the femtosecond laser beam. In this paper, we begin with an introduction of the princi

We experimentally investigate generation of backward 357 nm N _2 laser in a gas mixture of N _2 /Ar using 800 nm femtosecond laser pulses, and examine the involved gain dynamics based on pump-probe measurements. Our findings show that a minimum durat

We investigate lasing action in aligned nitrogen molecular ions (N_{2}^{+}) produced in an intense laser field. We find that, besides the population inversion between the B^{2}Σ_{u}^{+}-X^{2}Σ_{g}^{+} states, which is responsible for the observed s

We experimentally demonstrate the generation of narrow-bandwidth emissions with excellent coherent properties at ∼391 and ∼428 nm from N _2 ^+ (B ^2 Σ _u ^+ ( v ′ = 0) → X ^2 Σ _g ^+ ( v = 0, 1)) inside a femtosecond filament in air by an o

A novel method to achieve the coherence control of spatiotemporal coherency vortices of spatially and temporally partially coherent pulsed vortex (STPCPV) beams is proposed. The influence of spatial and temporal coherence of the source on the phase d

In this paper, we compare the properties of filaments generated in a Ne–N2 mixture, pure N2, a Kr–N2 mixture, and a Xe–N2 mixture pumped by femtosecond laser pulses systematically. Due to different nonlinear refractive indices and ionization po
