レーザーの自己導波の調査のため、長いunderdenseのプラズマと100TWレーザーパルスの相互作用実験を行い、レイリー長の約20倍の10mmという非常に長いプラズマチャネルを観測した。レーザーパルスがチャネル中で曲がること、及び電子キャビティ形成が実験的に初めて観測された。

An experiment for the laser self-guiding studies has been carried out with 100 TW laser pulse interaction with the long underdense plasma. Formation of extremely long plasma channel with its length, about 10 mm, 20 times above the Rayleigh length is observed. The self-focusing channel features such as the laser pulse significant bending and the electron cavity formation are demonstrated experimentally for the first time.
