Completed TRL 4 (started at 3, targeting 4)
Design and initiate lifetest activities on laser transmitter for the Cold Atom Gravity Gradiometer (CAGG) with funding from NASA STMD.
This proposed task is to initiate a path toward space qualifying the laser transmitters for gravity gradiometer. For the Gravity Gradiometer effort, we have prepared a plan to bring the laser systems to TRL6 in a 36 month program. An early start in performing studies in the optical, optomechanical, thermal and electrical systems that are required to mount, operate and inject light into and beam shaping the output beam is paramount in making the TRL-6 plan successful. We will use this IRAD task to begin an extended duration testing of these tapered amplifiers and understand the performance and degradation mechanism.

Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — 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.
