    New Far-Infrared Laser Lines and Frequency Measurements of Acetaldehyde and Vinyl Fluoride (1998)
    Springer
    International journal of infrared and millimeter waves 19 (1998), S. 719-726 
    Details
    ISSN: 1572-9559
    Keywords: far-infrared laser ; frequency measurement ; acetaldehyde (CH3CHO) ; vinyl fluoride (CH2CHF) ; cw CO2 laser ; new lines
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Eight far-infrared laser lines have been obtained by optically pumping acetaldehyde (CH3CHO) and nine by pumping vinyl fluoride (CH2CHF) with a cw CO2 laser. The far-infrared laser structure used a metal-dielectric waveguide cavity. This is the first reported observation of four of the laser lines in acetaldehyde. In this work, we measure the frequency, optimum pressure of operation, relative intensity, relative polarization, and pump offset from CO2 laser-line center.

    Laser Lines and Frequency Measurements of Fully Deuterated Isotopomers of Methanol (1998)
    Springer
    International journal of infrared and millimeter waves 19 (1998), S. 465-473 
    Details
    ISSN: 1572-9559
    Keywords: 12CD3OD ; 13CD3OD ; fully deuterated isotopomers ; new laser lines ; far-infrared laser ; frequency measurement ; CO2 laser pump
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Fully deuterated isotopomers of methanol (12CD3OD and 13CD3OD) were optically pumped with a CO2 laser. Five new far-infrared laser lines were discovered in 12CD3OD and 25 in 13CD3OD in the range 43.697 to 719.426 μm. The frequencies of these new and some previously reported laser lines, the pump offset, the relative polarization, the relative intensity, and the optimum pressure of operation were measured.

    Optically-Pumped Far-Infrared Laser Lines of Methanol Isotopomers: 12CH3OH, 12CH3OD, and 12CH2DOH (2000)
    Springer
    International journal of infrared and millimeter waves 21 (2000), S. 731-737 
    Details
    ISSN: 1572-9559
    Keywords: 12CD3OH ; 12CH3OD ; 12CH2DOH ; new far-infrared laser lines ; optically-pumped far-infrared laser ; laser frequencies ; relative intensity ; relative polarization ; pump-frequency offset
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Twenty-seven new far-infrared laser lines from the isotopomers of methanol: 12CD3OH, 12CH3OD, and 12CH2DOH, were obtained by optically-pumping the molecules with an efficient cw CO2 laser. The CO2 laser provided pumping from regular, sequence, and hot-band CO2 laser transitions. The 2-m long far-infrared cavity was a metal-dielectric waveguide closed by two, flat end mirrors. Several short-wavelength (below 100 μm) lines were observed. The frequencies of 28 laser lines observed in this cavity (including new lines and already known lines) were measured with a fractional uncertainty limited by the fractional resetability of the far-infrared laser cavity, of 2 parts in 107.
