Bessel-Gauss beams are known as non-diffracting beams. They can be obtained by
focusing an annularly shaped collimated laser beam. Here, we report for the first time on the …

An interesting feature of light fields is a phase anomaly, which occurs on the optical axis
when light is converging as in a focal spot. Since in Talbot images the light is periodically …

This study investigates the phenomenon of spatial frequency chirping in q-Gaussian laser
beams interacting nonlinearly with plasmas exhibiting an axial density ramp. The chirping …

Chirping of spatial frequency of q-Gaussian laser beams interacting nonlinearly with
plasmas with radially inhomogeneous electron density has been investigated theoretically …

We present a comprehensive review on the latest research activities that explore the Gouy
phase and indicate the recent experimental progresses for its observations in studies that …

We have studied in detail the situation wherein two microbeads are trapped axially in a
single-beam Gaussian intensity profile optical trap. We find that the corner frequency …

Gouy phase shift of q-Gaussian laser beams interacting nonlinearly with thermal quantum
plasmas (TQP) with axially increasing density has been investigated theoretically. The Gouy …

Recent shifts in congressional funding have prompted the development of methods for the
direct search for extant life within our solar system. In order to look for life elsewhere in our …
