Coherence Cloning Using Semiconductor Laser Optical Phase-Lock Loops [PDF]
, 2009 We demonstrate the concept of coherence cloning where the coherence properties of a high-quality spectrally stabilized fiber laser are transferred to a commercially available high-power DFB semiconductor laser (SCL) using an optical phase-lock loop.

FMCW RADAR SYSTEM FOR TRANSPONDER IDENTIFICATION
Progress In Electromagnetics Research B, 2018 —In this paper, we deal with a frequency modulated continuous wave (FMCW) radar used for localizing and tracking targets by frequency evaluation of the received radar beat signal. The radar system achieved with a primary radar (reader) and a secondary radar (transponder) is addressed as super high frequency (SHF) radio frequency identification (RFID ...
