When laser in or out of wave band was applied to detector subassembly of PC HgCdTe,some new phenomena are found that temperature of detector is increasing after laser stopping. Researches indicate that Ge window or filter absorbs laser energy is the direct reason that induces temperature increasing of detector. Experiments found that temperature increasing time of detector reduces when laser irradiated time increases and temperature increasing time of detector increase when laser power increases.
