Abstract:

Free electron laser FEL theory is extended to explain several effects associated with high gain operation. The trapped particle instability is reviewed for short pulses FELs, FEL oscillators, and FEL amplifiers. A new FEL theory exactly includes the effect of an arbitrary electron distribution function and an explanattion is given for optical self guiding. Keywords Free electron laser Trapped particle instability Laser oscillators Laser amplifiers and Review article.
