This proposal is for the development of an innovative, high power, and extremely reliable 1.26-micron Ho-doped fluoride fiber amplifier. The proposed fiber amplifier consists of a Ho-doped fluoride fiber pre-amplifier and power amplifier. Laser at 1187 nm will be used as a resonant pump laser source for Ho3+-doped fiber laser. High gain per unit length at 1.2 micron can be achieved in Ho-doped fluoride glass fiber due to the strong pump absorption at 1187 nm and strong emission at 1.2 micron transition. The proposed Ho-doped fiber amplifier will be implemented into a MOPA system with a 1.26 micron single frequency Ho-doped fiber laser.This type of fiber based seed laser is needed for remote sensing of O and O -N for measuring atmospheric pressure. Concurrent on-board O2 measurements using lines at 1.26 ìm to allow for the best relative compensation for aerosol scattering along the line-of-sight of the CO2 and O2 measurements. The particular O2 band was chosen so that the surface and atmospheric scattering characteristics from aerosols and thin clouds would be nearly the same as for the measurement of CO2 at 1.57 ìm. It's part of program to provide space-based active measurements of CO2 for Active Sensing of CO2Emissions over Nights, Days, and Seasons (ASCENDS) Mission.
