NEW CO2-LASER LINES IN THE 11-MU-M WAVELENGTH REGION - NEW HOT BANDS

摘要

[[abstract]]Nineteen new laser lines in the 11-mu m wavelength region have been observed in cw oscillation from a CO2 laser with a high-Q, high-resolution cavity at a higher than usual current density. The frequency of each line has been measured using heterodyne frequency measurement techniques. Analysis of the frequencies showns that 15 lines are rotation-vibration transitions of the 01(1)2-[11(1)1, 03(1)1](I) band (the first sequence hot band) of the CO2 molecule and four lines belong to the rotation-vibration transitions of the 02(2)1-[12(2)0, 04(2)0](I) band of CO2.
