Active Stabilization of Multi-THz Bandwidth Chirp Lasers for Precision Metrology

摘要

FMCW ladar using actively stabilized chirp lasers has many advantages for precision ladar applications. Active stabilization of the linear frequency sweep allows one to access the unmatched range resolution (～50 μm) provided by multi-THz bandwidth tunable laser sources in the telecom region at long ranges, large range windows, and without the need for computationally expensive post-processing.
