Direct Frequency Measurement of the 260 THz (1.15 μm) 20Ne Laser: And Beyond

  • Conference paper
Laser Spectroscopy IV

Part of the book series: Springer Series in Optical Sciences ((SSOS,volume 21))

Abstract

Absolute frequency measurement has been extended to the visible spectrum with the measurement of the strong 1.15 μm laser line in 20Ne at 260 THz and lines in iodine at twice this frequency. The 260 THz frequency was synthesized in nonlinear crystals of CdGeAs2 and AgAsS3 from stabilized CO2 lasers and the 1.5 μm laser line in 20Ne. The visible frequencies were synthesized by generating the second harmonic of the 260 THz radiation with a LiNb03 crystal. The absolute frequencies of ten hyperfine components of 127I2 near 520 THz were measured.

  10. The frequency of the 1.52 pm He-Ne laser was remeasured and the corrected value is listed. In the previous measurement (K. M. Evenson, D. A. Jennings, F. R. Petersen, and J. S. Wells, in Laser Spectroscopy III J. S. Hall and J. L. Carlsten, eds. (Springer-Verlag, Berlin 1977), pp. 56–68.), a higher frequency mode of the 1.52 pm laser was not detected, the CO frequencies were not directly measured, and the 1.5 pm laser discharge tube was filled to a total pressure of 324 Pa (with He:Ne=10:1) instead of the 648 Pa used in the present experiment. The new measurements, made with the 12C160, P18(14) line only, revealed the following corrections: (1) Mode +71 MHz; (2) directly measured frequency of 12060, P18(14) [“12C160 P18(14) = 48.862 075(3) THz] + 11 MHz; and (3) pressure shift [+65(9)kHz/Pa] + 21 MHz. The resultant frequency is v20Ne, 1.5 pm = 196.780 372(25) THz.
