Le. Vorobev et al., USE OF GE HOT-HOLE SUBMILLIMETER LASERS FOR METRICS OF NARROW-GAP SEMICONDUCTORS, Russian journal of nondestructive testing, 32(1), 1996, pp. 40-43
We describe a hot-hole submillimeter laser in which the wavelength is
tunable with simultaneous narrow-band emission. The laser is used for
inspection and certification of the parameters of narrow-gap semicondu
ctor materials.
