The DF (Deuterium Fluoride) chemical laser is produced by mixing fluorine gas with deuterium gas under special conditions to form DF lasers in an excited state. DF lasers produce a longer wavelength than other more traditional HF lasers, giving the user more effective laser transmission through the atmosphere. Spectra Gases’ unique position as a world leader in deuterium production provides our customers with the opportunity to use only the highest quality DF laser gas, and peace of mind from knowing that the technical expertise and service they receive from Spectra is second to none in the specialty gas industry.
