LaTso  Project

Evaluation and Standardization for Laser Damage Resistance of Aerospace Optics

        Our project aims to determine and standardize the laser endurance threshold (LHED) of optical components used in systems established for space research at different wavelengths (1064 nm, 532 nm, 355 nm and 266nm).

The LaTSO project aims to observe the behavior of the optical component in space conditions by creating a kind of simulation of space conditions in a laboratory environment. The experimental stages of the LaTSO project are listed below.

  • Determination of LHED under Atmospheric Conditions

  • Determination of LHED under Vacuum Conditions

  • Determining the LHED of thermally conditioned optical components

  • Determination of LHED of optical components aged with UV light
