Composite polymer-glass edge cladding for laser disks
This patent describes large neodymium glass laser disks for disk amplifiers such as those used in the Nova laser. They require an edge cladding which absorbs at 1 micrometer. This cladding, described in this patent, prevents edge reflections from causing parasitic oscillations which would otherwise deplete the gain. Nova now utilizes volume-absorbing monolithic-glass claddings which are fused at high temperature to the disks. These perform quite well but are expensive to produce. Absorbing glass strips are adhesively bonded to the edges of polygonal disks using a bonding agent whose index of refraction matches that of both the laser and absorbing glass. Optical finishing occurs after the strips are attached. Laser disks constructed with such claddings have shown identical gain performance to the previous Nova disks and have been tested for hundreds of shots without significant degradation.
