Abstract :
It has been demonstrated that silicon carbide (SiC) may be used as an efficient heatsinking material for intracavity face cooling of gain media in solid-state lasers. Comparative thermal modelling and temperature distribution measurements of a diode-pumped 4% Nd:YAG ceramic laser medium face cooled by undoped YAG (as a baseline), diamond and SiC lead to the belief that SiC is an effective replacement for much more expensive diamond in this application. Laser performance of a SiC face-cooled 4% Nd:YAG ceramic press-fit stack without AR coatings was demonstrated to have 24% slope efficiency
