A novel facet coating technology is presented by studying catastrophic optical mirror damage mechanism of semiconductor laser. In this technology
semiconductor laser are cleaved in the air
and the surface oxide layer is removed with a low energy ion source
flowed immediately by coating the facet with thin ZnSe layer of 20 nm. The function of this layer is to protect semiconductor laser facet
and prevent impurity particles diffusing to the facet. Finally the facet is coated with oxidative optical film. The test results show that the output power of the semiconductor laser with the ZnSe coated layer is 13% higher than that of the Si coated layer
and 47% higher than that of the oxide coated film. The device coated oxide film is damaged when current is 4.5 A
and the device coated with Si layer is damaged when current is 5.5 A
the final failed device is coated with ZnSe layer. In conclusion
the method of coating ZnSe layer on the semiconductor laser facet can prevent effectively the catastrophic optical mirror damage
and increase the output power of semiconductor lasers. 2010 IEEE.

Reaction Bonded (RB) SiC mirrors due to their excellent specific stiffness and thermal properties have been widely used in space telescopes. However
polishing large SiC aspherical mirrors is difficult compared to other materials such as fused silica or Zerodu. In addition
surface roughness of the polished SiC mirrors is limited by the defects of the materials and needs to be improved by means of surface coating technique. This paper introduces the current progress of large SiC aspherical mirrors manufacturing and testing in CIOMP. In particular
the procedures of making large off-axis aspherical mirrors were discussed in detail. A proprietary computer controlled optical surfacing (CCOS) technique was utilized to grind and polish the mirrors and the computer aided null test was used to measure the surface figure. As results
a 600mm class off-axis SiC aspherical mirrors was demonstrated with figure error less than 13nm rms.

The manufacturing procedure of a 500 mm in diameter
f/2 hyperbolic primary mirror based on Computer-Controlled Polishing is introduced in detail. The mirror was finally polished to the shape accuracy of 13 nm rms and the surface roughness of 2 nm Ra. Testing methods and data analysis for different stages ranging from grinding to polishing are discussed. Some critical factors affecting the efficiency and accuracy of the grinding/polishing procedure are summarized. In addition
the preliminary work to make large off-axis asphere mirrors is presented. The difficulties in polishing and testing for both circular aperture and rectangular aperture mirrors are previewed
and a possible solution is given. To control the geometrical parameters such as radius of curvature and conic constant
a new profiler has been built
and it has proven very useful to improve the grinding efficiency. Finally
the manufacturing of small aspheres using deterministic grinding tool is also introduced. The fine grinding procedure of LOH's asphere grinding machine is presented.
