Frequency-comb based approaches to precision ranging laser radar



Nathan R. Newbury, Tze-Ann Liu, Ian R. Coddington, Fabrizio R. Giorgetta, Esther Baumann, William C. Swann


The output of pulsed femtosecond lasers can be controlled to generate pulse trains with very precise timing and optical frequency. This source can be used in different ways to support precision coherent LIDAR. We will discuss several implementations of comb-based ranging including a system based on phase-locked dual comb transceivers, free-running dual-comb transceivers, and comb-assisted fm laser radar. We will present data from laboratory distance measurements using the two dual-comb approaches. We will also present data on the calibration of a fast swept laser using a frequency comb at rates of up to 1500 THz/sec.
