Abstract
This paper reports on the obtaining of supernarrow resonances in methane on the E-line of the P(7) transition of the ν3 band with a relative width of about 10-11 and on the use of such resonances for frequency stabilization of a He-Ne laser at 3.39 µm. The new results are presented of investigations on production of lasers with a limiting narrow line. The prospects of the development of works on optical frequency standards are discussed.
