Vibrationally Assisted Transfer Laser

摘要

Described are results from an experimental investigation of a novel concept forthe production of a short wavelength chemical laser (SWCL). The most promising approach for producing such a laser is through energy transfer pumping from a chemically produced, metastable species such as NF(a1Delta) and O2(a1Delta). Previous investigations have shown that species such as NF(a) and O2(a) can excite laser candidates such as BiF and IF. Our results show that preparation of the receptor species, e.g. IF(X), in high vibrational levels of the ground state can enhance the energy transfer efficiency dramatically. Our results also indicate that the process, which we call vibrationally assisted transfer laser (VATL), may have general applicability to the development of SWCL devices.
