PURPOSE: A device for measuring the strength of laser beams and a laser beam processing system using the same are provided to measure the strength of the laser beam's output by a laser generator with a simple low costing configuration. CONSTITUTION: A device for measuring the strength of laser beams comprises a voltage output unit(110), amplifiers(120), a voltage output terminal(130), an A/D converter(140), and a strength measuring unit(150). The voltage output unit outputs voltage corresponding to the strength of the laser beams. The amplifiers are connected to an output terminal of the voltage output unit respectively and consecutively in series, thereby amplifying the voltage output by the voltage output unit. The voltage output terminal is respectively connected to the output terminal of the voltage output unit and output terminals of the amplifiers, thereby outputting the voltage at corresponding positions. The A/D converter converts the voltage output to the voltage output terminal into a digital value. The strength measuring unit measures the strength of the laser beams using the converted digital value.
