1.57 µm fiber source for atmospheric CO 2 continuous-wave differential absorption lidar

Research output: Contribution to journalArticle


We present an efficient fiber source designed for continuous-wave differential absorption light detection and ranging (CW DIAL) of atmospheric CO 2 -concentration. It has a linewidth of 3 MHz, a tuning range of 2 nm over the CO 2 absorption peaks at 1.572 µm, and an output power of 1.3 W limited by available pump power. Results from the initial CW DIAL testing are also presented and discussed.
