Advantages

1. LaserStates has very strong capability in coating the different coatings on one substrate.
The transition area is straight, the width of transition area is less than 0.5mm

2. LaserStates has very strong capability in coating the Dielectric HR coating with Broadband and large AOI . The coating layer is very thick, and we assure the coating will not crack.

3. High LDT, LaserStates could offer high LDT HR mirrors. Following are pictures which show the mirrors were damaged when the laser pass through the mirrors

In order to get high LDT, LaserStates has several methods,
 
     a. Fast Coating, the substrates should be perform the coating after the polishing as soon as possible. Keep the Substrates "Fresh", otherwise, we should remove the oxidation film on the substrate then coat.
     b.  To improve the vacuum degree requirement of the coating chamber.
     c.   Improve the surface quality as high as possible.
     c.   Optimize the coating design.
