Abstract

A power stabilized butterfly-packaged diode laser (BPDL), which will be used as the calibration light source for the coronagraph module in the China Survey Space Telescope (CSST), was developed. An iris diaphragms (ID) was used to block the backscattering light from the end-face of coupling optical fiber. Additionally, the polarization direction of laser beam was adjusted to precisely coincide with the fast axis of the coupling optical fiber. The power of the BPDL was measured for four hours, resulting to the root mean square (RMS) value is smaller than 0.1% and the peak-to-valley (PV) value is smaller than 0.5%. Performances of the BPDL are presented. The developed BPDL can pass the aerospace environmental tests, indicating that the BPDL can be suitable for space missions.
