Summary
This article presents a design for the optical part of a Laser-Electron X-ray Generator for medical uses. It focuses on a passive optical circulator based on second harmonic generation and a picosecond laser system that can produce specific patterns of laser pulses (bursts). Two methods for generating these bursts using optoelectronic feedback with either a TaLiO3 or a DKDP crystal Pockels cell are proposed and tested. The DKDP crystal method allows for bursts with periods determined by the crystal's acoustic vibration modes.
