Increasing the output power of fast axial flow high power CO2 lasers requires a proportional growth of mass flow with the laser power for convective cooling of the active laser medium. Besides the demand on increasing output power the demand on small laser beam sources enforces the integration of all laser components in a tight assembly. By using compact turbo blowers it is possible to maintain a large mass flow with small and lightweight blowers within a compact beam source. In addition to experimental work a program for the simulation of closed gas circuits is presented as a tool for analysis and optimization. The structure of a typical flow system and its transfer to the program is presented. Results of calculations on closed loop flow systems and on open flow systems are presented. Varying basic parameters provides estimations on the overall performance of a modified laser system. With a similar approach applied to an open flow system requirements on central components can be listed.
