The NASArsquo;s Doppler Aerosol WiNd (DAWN) lidar system needs a pulsed single frequency laser operating near 2 micron lase wavelength. We propose a new type of Tm-doped fiber for this application. The overall objective of this proposal is to demonstrate and build a single frequency near 2 micron fiber laser with pulse energy of greater than 30mJ. Tm-doped gain fiber with excellent radiation resistance against high energy radiation will be used. This proposed laser will be all-fiber PM laser with a beam quality of 1.2. In Phase II we will demonstrate and deliver a packaged 2 micron single frequency fiber laser with 30mJ pulse energy to NASA.
