Three groups, one in the US at Berkeley, lead by W. Leemans1, one in England, lead by K. Krushelnick2 and one in France, lead by V. Malka3, have experimentally produced a monoenergetic electron beam using a short and intense laser pulse. This “dream beam” as it is called in the scientific journal, Nature, open new perspectives in the domain of accelerators.
The 1st Asian workshop on Generation and Application of High-Order Harmonics was held during Feb. 23-25, 2005 at KAIST, Daejeon, Korea. The workshop was organized to provide a forum for graduate students, junior and senior scientists from Asian countries, as a part of activities of the Asian Intense Laser Network.
First of all let me say I enjoyed meeting you all again on Friday/Saturday and I still feel a sense of excitement with the potential for this field. However this enthusiasm is somewhat tempered with realism which I though of bringing to the attention of the meeting. However there was not quite the opportunity and I certainly did not wish to in any way dampen the general feeling of euphoria.

The attached presentation touches on the ongoing research at the Rutherford Appletown Laboratory (RAL) on radiological protection.
By stretching, amplifying and then compressing laser pulses, one can reach petawatt powers, gigagauss magnetic fields, terabar light pressures and 1022 m/s2 electron acceleration.
