| Outline of Final Research Achievements |
Fast electrons accelerated through interactions of intense femtosecond laser pulses with solid target have great potential as a probe pulse to observe ultrafast phenomena, because they have advantages of high intensity and a short pulse. However, the most of the fast electrons cannot use as the probe pulse because they are trapped by a strong quasi-static electric field, called the sheath field, produced around the steep density gradient boundary. We proposed a solid-plasma hybrid cathode as a new target to increase the number of fast electrons escaping from the sheath field, and developed a short pulse electron beam generator with this target.
