Energy scaling of quasi-monoenergetic electron beams from laser wakefields driven by 40-TW ultra-short pulses
By focusing 40-TW, 30-fs laser pulses to the peak intensity of 1019 W/cm2 onto a supersonic He gas jet, we generate quasi-monoenergetic electron beams for plasma density in the specific range 1.5×1019 cm-3≤ne≤3.5...
