Dual-wavelength He-Ne laser running at 7.70 and 3.39 microm.
Two mid-infrared laser transitions in a He-Ne discharge have been investigated. They form part of a cascade transition and therefore have a power dependence, which has been examined and shown to satisfy the relationship P(7.70) = 410 + 0.63 x P(3.39), where P(7.70) and P(3.39) are the powers of the 7.70- and 3.3 9-microm lines, respectively, in micro-watts.
