Optical coherence extends beyond lasers, with partially coherent light enhancing imaging, communication, and photonic ...

Since last fall, NASA scientists have flown an advanced 3D Doppler wind lidar instrument across the United States to collect nearly 100 hours of data—including a flight through a hurricane. The goal?

Coherent light detection and ranging (LiDAR), particularly the frequency-modulated continuous-wave LiDAR, is a robust optical imaging technology for measuring long-range distance and velocity in three ...

In light of the phase noise characteristic of the PDH-locked laser, we can determine the relative phase noise of the two-color laser as (see Supplementary Note 1 for more information) $${S}_{\phi }^{{ ...
