Gold coated copper mirrors have a massive pulsed laser damage threshold, making them ideal for beam delivery and cavity mirrors.

Independent test houses have certificated Laser Beam Products mirrors as having a pulsed Laser Induced Damage Threshold of 46.7J/cm2 for a 80ns pulse. (500 MegaWatts!)

The reason for such exceptionally high damage resistance is the amorphous nature of the coating. Absence of crystal grains and grain boundaries means there is nothing on the mirror surface to initiate laser damage.

The amorphous nature of our proprietry coating allows "super smooth" chemically polished surfaces (surface roughness of 5nm or less) to be produced. There are none of the diffraction patterns, or target patterns so commonly seen on diamond machined metal mirrors.
