The inevitable objection raised, is that the apparently closed system produced by this arrangement cannot result in an output force, but will merely produce strain within the waveguide walls.

必定有人提出反对意见：显然，封闭系统不能输出对外的推力，但只会产生应变在波导内墙壁。

Then the calculation of the slab waveguide CO_2 laser with phase locking coherence output is described.

Crossing waveguide normalized output optical power versus intersection Angle in the main waveguide and power coupling versus intersection Angle are analyzed by the method.

在此基础上重点计算分析了大角度交叉波导的输出分支波导的能量与交叉角度的关系，以及交叉角度对波导间能量耦合的影响。

The output is then relayed into a 1.4 mm thick plastic waveguide lens with input and output hologram structures on the surface which squeezes the light down the waveguide and then two dimensionally expands the image back into the user's eye, creating an image that is then mixed into the real world.
