FIELD: measuring technology.
SUBSTANCE: invention is related to interrogating optical circuits and can be used in the manufacturing of semiconductor diode emitting laser modules for pyrotechnic systems. Technical result is achieved by the fact that the laser module for monitoring the integrity of the circuit in the pyrotechnic device contains a module with an additional low-power test laser diode with an emission wavelength that differs from the emission wavelength of the main laser diode and a pair of photodetectors designed to control the operation of the test laser diode, the main power laser diode and control the integrity of the optical circuit.
EFFECT: increase of reliability of the circuit and reduction of complexity of monitoring of integrity of optical circuits
