Research Abstract

本研究では、レーザービームを一対の誘導ブリルアン散乱(SBS)位相共役鏡の間に閉じ込め、レーザー光を往復させ、プラズマを通過中に複数回トムソン散乱させること(マルチパストムソン散乱)により、バースト的な高時間分解のトムソン散乱計測を実現し、この手法を確立することを目的として研究を進めている。本年度の主な成果は次のとおり。
1、位相共役鏡は単一縦モードレーザーを用いなければ高反射率を得ることができない。そこで、既存の2台のレーザー装置を組み合わせ、単一縦モードYAGレーザーを主発振器とし、その出力ビームを別のレーザー装置の増幅器で増幅する、ジュール級単一縦モードレーザーシステムの開発を行った。本年度は、レーザー電源を増力し、50Hz動作で1.15Jの出射エネルギーを達成し、マルチパストムソン散乱のためのレーザーの準備が整った。併せて、大口径ポッケルスセルを購入し、1対の位相共役鏡間にレーザーを閉じ込めるための基礎試験に着手した。
2、先進的なマルチパストムソン散乱計測に応用可能な、SBSパルス圧縮技術の開発を行った。本年度は、100ps以下のパルス圧縮を目標として、音響緩和時間40psの液体フレオン系化合物(ガルデンHT270)を用いて試験を行った。長さ1.5m、内径40mmのセルにHT270を充填し、f1000のレンズでレーザー光を集光し、SBSパルス圧縮を行った結果、パルス幅10ns、エネルギー1J、波長1064のレーザー光は、反射率90%で200ps程度まで圧縮できた。今後、動作条件の最適化を進める。
