Popis: We present the module of booster amplifier for coherent beam combining Master Oscillator Power Amplifier (MOPA) system to operate with a text narrow-linewidth seed laser. The goal was to achieve a highly modular system, manifested in the ease of changing the number of Coherent Beam Combining (CBC) channels. It uses a frequency tagging phase control scheme performed at acoustical frequencies, enabling a simple piezo fiber stretcher as actuating and tagging element and a cheap microcontroller to perform all the signal processing. The text four-channel CBC system with the proposed booster module was built to verify our assumptions and the whole system’s performance.
