Advanced Plasma and Laser Science Kenichi ISHIKAWA, Shuichi HASEGAWA, and Shinichiro KADO (Kyoto Univ.) （Tuesday, 16:40-18:20）

http://ishiken.free.fr/english/lecture.html (for course materials by Ishikawa) [email protected]

Kenichi Ishikawa (April 8 - May 27)

• high-intensity femtosecond laser-atom

interaction and attosecond science, one of the hottest field in laser science

Shinichiro Kado (June 3 - 17)

• Plasma production and diagnostics (Gaseous

discharge and plasmas, Optical Emission Spectroscopy, Laser-aided plasma diagnostics)

Shuichi Hasegawa (June 24 - July 15)

• Atomic spectroscopy of exotic atoms and

laser manipulation of isotopic atoms and ions

高強度（典型的には1013W/cm2以上）のレーザーパルスに照射され た原子や分子は、非摂動論的に非線形な応答を示す。 そのような高強度場現象の代表例は、超閾電離、トンネル電離、高 次高調波発生である。また、高次高調波は、極紫外から軟エックス 線領域の新しい超短パルス光源として応用され、アト(10-18)秒の時 間スケールで進行する原子分子内における電子ダイナミクスが明ら かになりつつある。 本講義では、レーザーの基礎に続いて、高強度場現象やアト秒パル ス発生について解説し、アト秒パルスの応用を紹介する。

With recent progress in laser technology, it is increasingly important to understand lasermatter interaction for atomic and molecular physics research as well as for materials processing and medical applications.
