Hybrid fiber/bulk laser source designed for CO and wind measurements at 2.05 µm.

We present a hybrid fiber/bulk laser source designed for CO and wind monitoring using differential absorption LIDAR (DIAL) and coherent detection at 2.05 µm. This source features a master oscillator power amplifier (MOPA) architecture made of four fiber stages and one single-pass, end-pumped, bulk amplifier.

2.05-µm all-fiber laser source designed for CO and wind coherent lidar measurement.

This work reports on an all-fiber pulsed laser source for simultaneous remote sensing of concentration and wind velocity in the 2.05 µm region. The source is based on a polarization-maintaining master oscillator power amplifier (MOPA) architecture.

Scanning wavefront folding interferometers.

We present modified scanning-type wavefront folding interferometers (WFIs), which allow spatial coherence measurements of non-uniformly correlated fields, where the degree of coherence is a function of two absolute spatial coordinates instead of coordinate separation only (Schell model). As an alternative to conventional prism-based WFI implementations, we introduce a scheme based on reflections by three mirrors. This setup allows us to avoid obstructions due to prism corners, and it is remarkably robust to polarization effects.
