| Abstract | ||
| A laser power comparator prototype that can be utilized in laboratories has been designed constructed and tested. The system consists of three main electronic circuits: the laser comparator electronic circuit, sign detector and phase inverting circuit, and an analog-to-digital readout display circuit. The comparator has two detectors each receives a particular input signal. Two input signals will be compared and the output will be displayed on a digital readout (or on an oscilloscope). Power difference up to 0.1mW is achieved. | ||
