The modification of mid-infrared radiation spatial profile caused by COP/ Ag hollow glass waveguide was investigated. The four laser systems - flashlamp pumped Er:YAG, Tm:YAG, and diode pumped Tm:YAG, and Tm:YAP laser sources - generating radiation in free-running regime were designed and constructed. The cyclic olefin polymer-coated silver hollow glass waveguide having an inner diameter of 700 μm and length up to 1.3 m was used as a delivery system base. The changes of beam spatial structures through the transfers system are presented. For Er:YAG laser the waveguide system was also investigated for bent cases. The energy transmission characteristics were measured for all systems.
