This development presents a TRL6 Laser Stabilization Unit featuring a high-finesse Fabry-Perot cavity for ultra-precise inter-satellite laser interferometry. The system utilizes an ultra-low expansion spacer, advanced thermal shielding, and a Pound-Drever-Hall signal detection scheme. These improvements ensure the frequency stability necessary for future gravitational field mapping missions.
