The resonance - enhanced multi - photon ionization ( rempi ) spectrum of no in the region of 420 - 680nm is obtained by using optical parameter generator and amplifier ( opg / opa ) as radiation source . the opg / opa was pumped by nd : yag ( quantel ) laser 本工作以超短脈沖( 35ps ) nd : yag激光的三倍頻輸出( 355nm )泵浦光學(xué)參量發(fā)生放大器作為激發(fā)源,獲得了no分子在420 680nm波長(zhǎng)范圍內(nèi)的多光子共振離化光譜。
