Abstract
A laser gain medium has a diamond coating in order to strengthen it and reduce parasitic oscillations. The medium can be a slab with chamfered corners with the coating on the edge faces and the corners, or a rod with the coating going all the way around it to eliminate stress corrosion and provide a compressive stress. The medium can be Nd:YAG and the coating can have a parasitic absorbing dopant. In a laser, the length of the coating preferably is the same as the length of the medium. For the slab, siderails can be used with a length slightly shorter than that of the coating.
