Conclusions
-
1.
This method of laser frequency measurement in the submillimeter range provides a measurement error of about 2.1·10−7, which is due mainly to instability in the laser and to the method of tuning to the emission peak.
-
2.
The frequency at λ=0.337 mm for CH4+N2 is measured as 890754.07±0.19 MHz. The standard deviation is σ=±0.2 MHz and agrees approximately with the calculated value.
-
3.
Measurements of the gain line width give a result in agreement with [5] within the error of measurement. Work is in hand on stabilizing the laser frequency via the difference frequency.
