Tunable High-Power Single-Frequency Laser at 2050 nm

Completed Technology Project

Project Description

Final Summary Chart Image
We propose a novel new architecture for a low-phase noise electronically tunable laser single-frequency laser at 2.05 microns that meets all the demanding requirements as a seed laser for NASA Lidar applications measuring CO2 densities in the atmosphere. The laser technology is based on previously developed hybrid integration technology that enables the direct optical coupling of active and passive waveguide chips. Array scaling was previously demonstrated for a 4-channel IFOG optical engine and this technology will be applied to the development of the array-scalable tunable laser. The proposed tunable laser can address LIDAR applications at 2.05 microns and can be modified to any wavelength spanning the range of 640-2500 nm. More »
