Energy efficiency of an intracavity coupled, laser-driven linear accelerator pumped by an external laser

چکیده
1098-4402= We calculate the optimum energy efficiency of a laser-driven linear accelerator by adopting a simple linear model. In the case of single bunch operation, the energy efficiency can be enhanced by incorporating the accelerator into a cavity that is pumped by an external laser. In the case of multiple bunch operation, the intracavity configuration is less advantageous because the strong wakefield generated by the electron beam is also recycled. Finally, the calculation indicates that the luminosity of a linear collider based on such a structure is comparably small if high efficiency is desired.

Energy Efficiency of Laser-Driven Accelerator Based on Photonic Crystal
We calculate the optimum energy efficiency of photonic crystal fiber based, laser-driven linear accelerator by adopting a simple linear model. In the case of single bunch operation, the energy efficiency can be enhanced by incorporating the accelerator with an intracavity pumped by external laser or gain medium. In the case of multiple bunches operation, the incorporation of intracavity is some...
متن کاملExperimental Study of a Flash-lamp Pumped Passively Q-Switched Nd:YAG Laser Using Cr4+:YAG Saturable Absorber
This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...
متن کاملTheoretical Study of Diode Pumped Intracavity Doubled Passively Q-Switched Solid-State Lasers
In recent years, great attention has been paid to high peak power all-solid-state pulsed blue-green lasers [1–4] for some applications such as spectroscopy, display, optical data storage, coherent telecommunications, remote sensing, medicine, etc. Such lasers are generally realized by intracavity or external cavity frequency doubling of cw laser-diode (LD)-pumped solid-state Q-switched Nd-doped...
متن کاملCompact 4.7 W, 18.3% wall-plug efficiency green laser based on an electrically pumped VECSEL using intracavity frequency doubling.
We have demonstrated a compact, 4.7 W green laser based on an electrically pumped vertical external-cavity surface emitting laser through intracavity frequency doubling. The overall wall-plug efficiency (electrical to green) was 18.3%. The power fluctuations were measured to be ±1.4% over a 2 h time period.
متن کاملCompact, passively Q-switched, all-solid-state master oscillator-power amplifier-optical parametric oscillator (MOPA-OPO) system pumped by a fiber-coupled diode laser generating high-brightness, tunable, ultraviolet radiation.
We report on a compact, tunable ultraviolet laser system that consists of an optical parametric oscillator (OPO) and a longitudinally diode-pumped Nd:YAG master oscillator-power amplifier (MOPA). The pump energy for the whole laser system is supplied via a single delivery fiber. Nanosecond pulses are produced by an oscillator that is passively Q-switched by a Cr(4+):YAG crystal. The OPO is pump...
