Integrally packaged laser detector

According to the integrated packaging laser detector, a circuit board is arranged in an airtight metal tube shell, a passive light path board is arranged above the circuit board, a laser chip is arranged on the passive light path board, a passive light path is a focusing light splitting light path, and three detector chips are arranged on three receiving light paths of the focusing light splitting light path; according to the invention, the laser and detection chip, the passive focusing light splitting optical path and the driving chip are packaged in the same packaging body, so that the communication distance between the chips is effectively shortened, and signal interference is reduced; in the aspect of optical coupling, the laser chip and the detector chip are directly subjected to optical path light splitting coupling in a packaging body, and the coupling efficiency is improved; and the size of the packaging body can be greatly reduced. 本发明一体化封装激光探测器，在气密的金属管壳中设有电路板，电路板上方设置无源光路板，无源光路板设有激光芯片，无源光路为聚焦分光光路，聚焦分
