Abstract
Describes a device with a long pulse-high energy ruby laser (1.5 ms, 50 J) appropriate for measurements at small and medium electron densities. Correction for the plasma radiation (continuum and weak line radiation) and improvement of the signal to background ratio by adequate rejection of the stray light of strong lines is necessary in that case. The authors obtained a high rejection by using a grating in combination with an optical filter. The device built up according to this principle is a simply handling small volume system at a relatively low cost. The applicability of the device is tested with a hollow cathode arc as a plasma source; the electron density and temperature ranges of the argon plasma used were 5*10/sup 18/-8*10/sup 20/ m/sup -3/ and 2.5-4.5 eV
