P. Balling et al., INTERNATIONAL COMPARISON OF I-127(2)-STABILIZED HE-NE LASERS AT LAMBDA-APPROXIMATE-TO-633 NM USING THE 3RD AND THE 5TH HARMONIC LOCKING TECHNIQUE, IEEE transactions on instrumentation and measurement, 44(2), 1995, pp. 173-176
In an international comparison of I-127(2)-stabilized helium-neon lase
rs at lambda approximate to 633 mm, lasers from the CMI and the BIPM w
ere stabilized by the third (THT) and the fifth (FHT) harmonic locking
techniques. A frequency shift to the blue was measured when using the
FHT technique. The influence of weak components of the rotational-vib
rational transition P(33) 6-3 of the molecule (II)-I-127-I-129 On the
frequency shift of components d, e, f, and g of the line R(127) 11-5 i
s evaluated.
