Synthesis of coherent optical pulses using a field-programmable gate array (FPGA)-based gradient descent phase-locking algorithm with three semiconductor lasers

We demonstrate optical pulse synthesis through coherent combination of AOM-separated light by phase-locking feedback from an FPGA. An order of magnitude improvement in phase stability is shown, limited by the noise of the AOM driver.
