Abstract:

Line structure of the phosphate–neodymium-glass laser generation spectrum within the 1.3 μm region is investigated. It is shown that the structure is determined by the presence of atmospheric air in the laser cavity. Its elimination has made it possible to create an intracavity laser spectrometer with the threshold sensitivity of 3•10–8 cm–1. The spectrum is recorded using a vacuum spectrograph by the method of nonlinear frequency conversion (doubling and mixing frequencies) as well as by direct recording of the spectrum on a film.
