Microwave Modulation

Abstract Infrared spectroscopy with laser sidebands at microwave modulation frequencies Infrared spectroscopy with laser sidebands at microwave modulation frequencies (12-18 GHz) is described. After the basics of this technique several examples of saturation spectroscopy on gaseous molecules are given. As a result it is shown that, in the infrared between 900 and 1100 cm-1 this broadband tunable laser source achieves resolution (3 parts in 109) as well as absolute accuracy in frequency measurement (± 3 x 10-6 cm-1) which are comparable to microwave spectroscopy.

Frequency Stabilized Laser

In this paper, frequency-stabilized laser technology is introduced into photodetector frequency response measurement system. A 1531nm frequency-stabilized laser fulfilled by acetylene saturated absorption is employed to produce coherent light with a tunable laser source, gaining stable beat frequency light that reaches as high as several hundred ghz, fulfilling measurement of 40ghz high-speed photodetector frequency response bandwidth, and lowering impacts caused by instability of light frequency. In addition, measurement uncertainty analysis is conducted, which is better than 7 %(k=2).
