 note = {The beat-wave laser had first demonstrated a laser can accelerate the electrons to above 20 MeV through a relativistic plasma waveIt was because the beat wave excites the plasma wave more effectively than any other laser acceleration scheme, such as a laser wake field Two 0.1 TW lasers, oscillating at 810 nm and 790 nm, respectively,  will resonantly excite a plasma wave at the plasma density of 1 x 1018cm-3 and produce the maximum electron energy of 30 MeV. 
We are constructing the Ti:Sapphire laser system on a 2 m-wide x 5 m-long table whose output will soon illuminate a capillary target and generate energetic electrons., 19th ICNSP&APPTC},
