Infrared laser concepts that have high efficiency or high power applications are being studied. As part of this interest, the possibilities of lasing homonuclear molecules such as H2 or N2 directly without the use of permanent dipole additives have been analyzed. Basically the idea is to produce an inversion in a gas by a high-pressure e-beam-stabilized electric discharge and then induce radiative transitions via collision partners or electric fields. In H2, gain has been predicted over a bandwidth extending from 2.7 micrometers to 10 micrometers using the principle of collisionally induced dipole. In the search for new lasers having the possibility of increased efficiency, the N2-DCl and D2-HCl molecular systems have also been analyzed as examples of possible v-v transfer lasers. Experimental aparatus in the form of a low pressure mixing laser setup was built and used as a means for preliminary study.
