The application of porous foam structure cooling arrangement system for a thin disk laser

We have studied a porous foam structure cooling arrangement system that has a better uniformity than an ordinary mini channel cooling system. It can be seen from the finite element analysis model that the results of disk crystal temperature distribution during the operation of the thin disk laser (TDL) demonstrate a significant advantage in terms of uniformity and heat transfer coefficient. In the comparative experiment, we realized a 150 W continuous wave pump with a 24-multipasses pumping structure; the optical-to-optical efficiency reached 49.3%. This proves that the porous foam structure cooling arrangement system has better heat exchange effect and uniformity than the cooling system without porous foam.
