Terahertz radiation generation by beating of two spatial-Gaussian lasers

Multifocal terahertz radiation by intense lasers in rippled plasma

“…Here, we clearly observe that the lasers with lower beam width produce intense radiation and the same is the case with higher index lasers (p). These results are in agreement with the observations made by other researchers [24][25][26].…”

Electromagnetic Waves and Their Application to Charged Particle Acceleration

“…Since the amplitude of resonantly excited wakefield changes at a faster rate with the waveguide width, pulse duration and microwave intensity and it is larger for the smaller waveguide width, longer pulse duration and the higher microwave intensity in the case of rectangular triangular pulse, the significant wakefield can be excited in the waveguide and effective particle acceleration can be achieved with the use of RT pulses for which the parameters can be optimized using the present studies. This theoretical work on the contribution of different microwave and laser pulses for the purpose of particle acceleration and the THz generation [100,101] shall induce experimentalists to develop rectangular, rectangular-Gaussian, rectangular-triangular, sawtooth and triagular pulses of appropriate lengths for accomplishing various experiments on wakefield generation, particle acceleration, and the THz generation. Through such efforts our researchers would be able to benfit the society more via the medical, scientific, and technological applications of the subject electromagnetic wave and plasma interaction.…”

Strong Terahertz radiation generation via wakefield in collisional plasma

“…The researchers all over the world are putting their efforts to generate the THz radiation sources where the laser plasma interaction has vital role to play. There are a lot of studies on laser plasma interaction, which talk about different mechanisms [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Extremely powerful THz radiations have been achieved by interaction of chirped [24], few cycle laser pulses [25] and tailored laser pulses [26] with plasmas.…”
