It indicated that a-C: F films deposited at higher microwave power have a better thermal stability. And the films deposited at R. T were mainly composed by CF2 and CF as well as C=C bonding. F is desorbed with C with the form of CFx at lower annealing temperature and the transformation of the band state of C atom from SP* to SP2 occurs at higher annealing temperature which enhances the C=C bonding of a-C:F film. Thefilms take on amorphous structure even after 400C annealing. There is a close relationship between relative concentration of C=C bond and optical band gap and a lower optical band gap corresponds to a better thermal stability. Both dielectric constant and dielectric loss increased after annealing due to the loss of F and enhanced orientation polarization, respectively.
结果表明，高微波功率下制备的a-C：F膜具有较好的热稳定性；室温下沉积的薄膜主要由CF_2和CF键和C=C键构成，当退火温度较低时，C与F成分主要以CFx的形式从膜中逸出，当退火温度继续升高后，部分SP~3C转变成Sp~2C，使膜中C=C键含量增加；a-C；F薄膜经历了400℃热处理后仍为非晶结构；薄膜C=C键含量与光学带隙之间存在密切的关联，低的光学带隙对应较好的热稳定性；退火山氟的逸出导致了介电常数增大，薄膜取向极化的增加使得介电损耗增大。

As the molar ratio of Sn and CdTe increases, the preferential orientation of (111) in films becomes weaker, the grain size becomes smaller, and the crystal boundary becomes indistinct, which indicates that the crystallization growth of films is incomplete. However, as the Sn content increases, optical absorption becomes stronger in the visible region.

To make the cavity more stable, a new kind of end-mirror shelves without knobs are used. Adjust the orientation of the mirrors through grinding the three frustum at the bottom to proper height, but the precision is limited. For this, we insert a double-optical wedge into the cavity and adjust the cavity to the best through rotating the double-optical wedge. Besides, the double-optical wedge has another function here. As we know, after long time laid, the laser in the cavity may deviate from the original aspect more or less, and this will reduce the output power. But here only through adjusting the double-optical wedge can compensate the power to the original.

Finally the article expresses accurately all these factors by a single variable called lagging angle which is the projective angle of the winding angle on level, and obtain the quantitative relation between the lagging angle and the clearance of optical fibre loops or the orientation which winding optical fibre tends towards.
