H2O, NO, and N2O infrared lasers pumped directly and indirectly by electronichyphen;vibrational energy transfer

摘要

Pulsed infrared molecular lasers are reported in which pumping is via electronichyphen;vibrational energy transfer from Br(42P1/2). H2O and NO lasers are pumped directly byEhyphen;Vtransfer and operate on a variety of transitions not previosuly seen in stimulated emission. The N2O laser operates near 10.9 mgr;m and is pumped by a twohyphen;step process involvingEhyphen;Vtransfer to an intermediate molecule and subsequentVhyphen;Vtransfer from that molecule to N2O. This latter technique extends the applicability ofEhyphen;Vpumping to molecules which do not interact directly with the electronically excited species.
