输入激光能量耦合到空心玻璃波导中的方式对波导的衰减和输入端加热有很大影响。耦合条件的理论讨论与波导损耗和局部加热有关，这可能发生在耦合未优化时。我们的研究结果表明，最大传输的最佳耦合不一定等于最低阶HE 11模式的最佳耦合。此外，它表明，这些波导的输入端加热可以大大减少传输的影响最小，如果波导孔尺寸是大的。(C)1998年，由光学仪器工程师学会（Society of Photo-Optical Instrumentation Engineers）主办。
The attenuation and input end heating of hollow-glass waveguides are greatly affected by the way in which the input laser energy is coupled into the guides. A theoretical discussion of coupling conditions is related to waveguide loss and local heating, which can occur when the coupling is not optimized. Our results indicate that the optimum coupling for maximum transmission is not necessarily equivalent to optimum coupling to the lowest order HE11 mode. Additionally, it is shown that the input end heating of these waveguides can be reduced substantially with minimal effect on transmission if the waveguide bore Size is large.
