Vacuum Laser AccelerationLaser Phase VelocityVLAUsing the BNL Accelerator Test Facility we have shown that a tightly focused laser on a vacuum can accelerate an electron beam in free space. The electron beam had energy of 20 MeV and the CO2 laser had energy of about 3 Joule. In the readout...
The purpose of the communication is to comment on and discuss laser acceleration of electrons in vacuum. In particular, the authors: (i) critique the recent paper by C.M. Haaland, titled ldquoLaser electron acceleration in vacuumrdquo (see ibid., vol. 114, p. 280 (1995)), (ii) discuss...
Accelerating particles to relativistic energies over very short distances using lasers has been a long-standing goal in physics. Among the various schemes proposed for electrons, vacuum laser acceleration has attracted considerable interest and has been extensively studied theoretically because of its appeal...
Exact closed-form solutions to Maxwell's equations are used to investigate the acceleration of electrons in vacuum driven by ultrashort and nonparaxial radially polarized laser pulses. We show that the threshold power above which significant acceleration takes place is greatly reduced by using a tighte...
AccelerationWe explore the electron dynamics in a Gaussian laser pulse to assess the contribution of the temporal parameters to the mechanism of vacuum laser acceleration. Our numerical study reveals that a considerable nonzero energy gain can be achieved through a spatio-temporally controlled electron ...
Ultrahigh-gradient acceleration, by a chirped circularly polarized (CP) laser pulse in the presence of a planar magnetic wiggler, is investigated numerically. A simple linear chirped profile of laser frequency has been introduced in our model. The combined effect of frequency chirping and the tapered...
The described changes in the structure of the transmitted beams impact the acceleration of electrons in vacuum. Our primary focus is on the relative differences between the simulations with \({n}_{\max }=2.5\) and \({n}_{\max }=0.5\). We use Eq. (18) to find that for the accelera...
The dependence of the electron-energy gain on the on-axis laser intensity of a TEM00 light wave in vacuum, called the capture and acceleration scenario (CAS), has been studied. We found that there exists a laser intensity threshold for the CAS scheme to work. The physical meaning of the ...

This study investigated electron beam laser excitation in the UV region using a GaN/AlGaN multiquantum well (MQW) active layer. Laser emission was observed when the GaN/AlGaN MQW was excited by an electron beam, with a wavelength of approximately 353
