The new variant a trap detect or design is shown. All of three detector photodiodes are connected in parallel. Absence of adjusting elements for each photodiode essentially simplifies of trap detector assembly and raises the mutual orientation stability of photodiodes during its operation. The developed variant a trap detector is intended for absolute value measurement, of the laser radiation power in an optical range with a relative error at a level of several tenths of percent.
