Paper Abstract

This paper reports experimental work towards a laboratory standard based on the 20Ne transition at 1.523 micrometers , some calibration measurements to 2.5 parts in 107 on lines of C2H2 between 1.52 and 1.545 micrometers , and investigation of a standard at 1.56 micrometers involving a CO line. Progress is described towards measurement of the latter line by frequency doubling to, and beating against, a Rb D2-line stabilized laser at 0.780 micrometers of known frequency.
