| Research Abstract |
Laser accelerated electron beam via laser-plasma interaction has an ultra-short pulse width. The expected pulse width is the order of femtosecond (1 femtosecond = 1/(1 quadrillion) second). The electron beam will be a source for measurement of the chemical reaction and the control.
In this research, a stable electron beam generation and a pulse width measurement are conducted. As a target, helium gas is used due to the safety and the easy estimation of the plasma density. By changing the target to nitrogen, we have succeeded the stable electron beam generation. Furthermore, we have succeeded to measure the pulse width of the electron beam. The electron beam is oscillated in the laser field. From the oscillation, 1.7 femtosecond of the pulse width has been measured.
