Frequency stabilized system of the reference laser diode for space-borne Fourier transform spectrometer

A frequency stabilized system of the laser diode is described in this paper. It consists of two parts: the temperature controlling module and the driving current modulating module. The principle and construction of the system are analyzed. Experiments are conducted and data are obtained. It is found that the temperature stability is better than 0.01 K and the stability of the current source is better than 10 uA.
