Radiative collisional laser feasibility demonstration
Abstract
Collisional radiative process between metastable state He and ground state N2 has investigated through two separate experiments: gain/absorption in electron-beam excited He/N2 gas mixtures, and change of He metastable density in the presence of external photon flux. No net gain was observed in He/N2 system as it was presumably overwhelmed by the background absorption. However, the preliminary results of our He metastable density measurement gives strong evidence for existence of collisional radiative process.
