Enhanced electron acceleration through Hermite higher-ordered cosine-hyperbolic-gaussian laser in vacuum
Theoretical investigation on Hermite higher-ordered cosh-Gaussian (H-Hch-G) laser pulses to explore their potential for effectively vacuum electron acceleration. The Hermite polynomial function with mode indices (n, l), decentered parameter (b) governed cosine-hyperbolic function, its higher-order (m), and Gaussian beam function all affect the propagation properties of these distinct laser pulses. With an order of ‘m’ varying from 0 to 3, they are categorized as HG, H-cosh-G, H-(cosh)2-G, and H-(cosh)3-G functioned laser pulses. It is suited for long-distance propagation because the beam profile departs its initial maximum intensity centre more slowly and becomes flatter as ‘m’ increases. Upon changing ‘b’, the property’s characteristics changes from ring-shaped (b ~ 2) and flat top (b > 1) to Gaussian (b = 0). Consequently, it functions sufficiently to quickly accelerate electrons to incredibly high energies. According to analytical findings, there is a large increase in electron energy in GeV regime with intensity peak ~\(\:{10}^{20}\text{W}/{\text{c}\text{m}}^{2}\) of laser in vacuum when the mode indices (n, l), m and b are altered.
