The generation of terahertz (THz) waves via the beating of two high-intensity chirped Gaussian lasers in a multi-ion-species plasma is numerically studied by taking into account the weak relativistic and ponderomotive regime of interaction. The coupl

Terahertz (THz) radiation generation by nonlinear coupling of two color Gaussian laser beams in a plasma with multi-ion species is numerically investigated by taking into account the nonlinearity due to ponderomotive force and space-charge field. By

In real thin disk laser systems, a fraction of absorbed pump power is dissipated as heat. Consequently, the thin disk lasers experience a temperature gradient in the axial direction of the disk which produces inhomogeneous stress and strain distribut

Edge-pumping is very advantageous for pumping disk lasers because it provides a long absorption path for the pump compared with end-pumped one. In the current work, we report an edge-pumped Yb:YAG disk laser pumped from four sides with diode laser st

This paper presents an investigation of the characteristics of the propagation of a Gaussian laser beam through an underdense plasma in the presence of a linear electron temperature ramp. Relativistic and ponderomotive nonlinearities are involved. It
