Abstract

The frequencies of twelve carbonyl sulfide absorption lines near 9.5 μm have been measured by means of a heterodyne frequency measuring technique, which uses a frequency stabilized CO2 laser and a tunable diode laser. The diode laser was locked to the peak of each OCS absorption line by means of a first derivative frequency lock procedure. In addition to lines in the 0200–0000 band, measurements also include some nearby OCS hot band features as well as lines in isotopically enriched samples of OC34S, O13CS, and 18OCS. These measurements are part of an effort to provide frequency standards for the calibration of tunable IR laser devices.

Block diagram of a TDL spectrometer with capabilities for heterodyne frequency measurements. This arrangement permits locking a liquid helium cooled TDL to some absorption feature of the OCS molecule and then making frequency measurements relative to a stabilized CO2 laser. Use as a conventional TDL spectrometer is facilitated by inserting a chopper in front of S1 and moving the upper mirror to the dashed position for interpolation with the Fabry-Perot fringes.

Fig. 2

(a) Rectified signals from tunable diode laser and CO2 laser radiation. The detector was connected directly to the scope, which was adjusted to a 10-mV/division display. The lower frequency 40-mV chopped signal is due to the CO2 laser. Detector nonlinearity is evidenced by the TDL signal, which drops from nearly 5 mV with the CO2 laser off to about 1 mV with the CO2 laser on. (b) Beat note between TDL (near P(41) of the OCS molecule] and the P(36) line of the CO2 laser. The TDL current was about −0.69 A, just slightly above threshold. The center frequency is 530 MHz, and the dispersion is 10 MHz/cm. Other spectrum analyzer parameters are linear display, 300-kHz bandwidth, and 10-msec/cm sweep rate.

Fig. 3
Fig. 3

(a) The derivative signal as the TDL was swept through an OCS line is displayed as a function of TDL current. The residual fringes on this signal are difficult to eliminate and are included in the error limit for our measurements. Zero voltage and an error voltage when lock loop is closed are also indicated. The lock point for the frequency measurements is the intersection of these three lines. (b) Beat note (linear display) between TDL, which is locked to a carbonyl sulfide line, and the P(32) line of the CO2 laser. The center frequency is 507 MHz, and the dispersion is 10 MHz/cm. The dark void in the center of the beat note is due to a marker oscillator which is simultaneously fed to a counter for an accurate frequency determination. The 10-MHz linewidth of the beat note is due primarily to the frequency modulation used for the first derivative locking signal.
