Paper Abstract

The performance change of photovoltaic (PV) indium stibium (InSb) detector illuminated by continuous wave (CW) chemical oxygen iodine laser (COIL) with different power density was measured and the damage threshold interval of the detector was achieved to be 26(0.89S) approximately 113(1.4S)W/cm2. Using the integrating sphere technology, the thermal coupling coefficient of InSb crystal material to CW COIL was measured to be 0.664 +/- 0.004. Compared with the theoretical result, the thermal coupling coefficient measured was a little bigger due to the effect of the surface defect of InSb material. The principle and damage mechanism of PV InSb detector was reviewed. The temperature rise and performance change of PV InSb detector illuminated by CW COIL were calculated with 1D thermal model. The calculated results was consistent with the experimental results.
