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.
A temperature controller is designed to stabilize the temperature of a laser diode in the Spaceborne Fourier Transform
Spectrometer. The principle and construction of the temperature control scheme are analyzed in this paper. Experiments
are setup and data are obtained. It is found that the temperature stability is better than 0.01 k.
