High Stability Optical Mount for Space Laser Applications
In the frame of Atmospheric Lidar (ATLID) project, one of the active instruments foreseen to be boarded on the EarthCARE satellite, a high stability optical mount has been designed, developed and tested in order to fulfil the tight program requirements. A description of the design solution developed, manufactured and qualified for the most critical optical mount inside the PLH, located on the Laser Master Oscillator Plate (the laser resonance cavity), is presented. In order to minimize optical mount mass and envelope, the developed solution foresees a glued interface (I/F) between the mechanical support and the mirror. A collection of stability results obtained on the optical mount breadboards is also presented, including a description of environmental tests performed and the way to assess the mirror stability after each environmental test, as well as the acceptance criteria derived in order to establish the flight worthiness of the manufactured and assembled hardware.
