High Reflectivity Mirrors
Overview
Key Problems
Short duty cycle and lifetime of laser optics caused by coating absorption and laser damage.
Beam profile deformation
Polarization sensitivity requires beam delivery components to be optimized for s and p at the same time.
Multiple wavelengths coverage in the system.
