Compact and Highly Efficient Multi-Purpose Laser, Year 1

Many future NASA sensors will employ lasers to measure parameters of the atmospheres and surfaces of Earth and other planets, and to assist navigation and operation of space vehicles and aircraft. These sensors would benefit tremendously from increases in efficiency and laser power, with corresponding decreases in mass and power budgets. A new laser concept capable of generating relatively high pulse energies with over an order of magnitude higher efficiency and about a third of the mass of current lasers is being developed. Conventional solid-state lasers can generate high pulse energies but suffer from low efficiency. Fiber lasers offer optimal efficiency, but they cannot produce required pulse energies for most NASA applications. A novel hybrid fiber/solid state laser for generating relatively high pulse energies with over an order of magnitude higher efficiency and about a third of the mass of current lasers is proposed. High spatial and spectral beam quality of the laser can improve the instrument sensitivity and precision. The new laser architecture can be implemented at any of the fundamental wavelengths of 1.0, 1.5, or 2.0 microns. The successful demonstration of this novel laser will profoundly affect the design of all infrared lasers for a wide range of applications from medical to military, and from telecommunication to manufacturing. Due to much reduced power, size, and mass, this laser will allow for significant cost saving in deployment of instruments in space thus creating new opportunities for Earth and planetary observation systems.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
