In a compact laser measuring device with a high level of transmission power the problem arises of the laser detector being dazzled by unwanted stray light.To resolve that problem there is provided a module (2) for a laser measuring device (4) which includes a laser source (6, 36), a transmission light guide (8, 38a-d) optically connected to the laser source (6, 36), a laser detector (10), a reception light guide (12) optically connected to the laser detector (10), a transmission reception light guide (16, 42a-d, 54) and a coupling element (14, 40a-d) which optically connects the transmission reception light guide (16, 42a-d, 54) to the laser source (6, 36) and the laser detector (10), wherein the transmission reception light guide (16, 42a-d, 54) is operatively connected to a light amplifier element (22).
