Abstract
Systems and methods for laser based measurement of air parameters are disclosed. An example system includes a source of radiation, an amplification system with one or more power amplification stages, a transceiver, and an optical mixer. The source produces a plurality of beams, and the amplification system is configured to amplify the beams. The transceiver is configured to transmit the modulated beam to, and receive a scattered beam from a target region. The optical mixer is configured to determine a difference between the scattered beam and a reference beam, which is used to determine a Doppler shift therefrom. In certain embodiments, the amplification system includes a fiber preamplifier and one or more fiber power amplifiers stages.
