Design and operation of He-Ne laser with U-shaped optical path in cavity are described; output power in 2 m long tube is about 60 mw at lambda equals 6328 A; amplification of active medium at generation threshold, as well as cavity losses were also measured. (see also English translation in Soviet J Optical Technology v 34 n 3 May-June 1967 p 273-4) (48742)
