Abstract
The laser pulse waveform real-time precision measurement technology based on time division multiplexing (TDM) was developed for all fiber multi-beam high repetition frequency laser system. According to the characteristic of the system, we designed a kind of 1×8 optical time division multiplexer and a kind of 1×2 optical time division multiplexer with different time delay. Also we experimentally demonstrated the technology in the system, the results show that the pulse duration, pulse energy and rise time could be accurately measured, and meanwhile the system working status could be inspected in real time.
