Abstract
An epoxy-free method for manufacturing a faceplate for a laser-CRT that produces a uniform bonding interface between the laser structure and the transparent substrate during faceplate fabrication such that efficient uniform optical output, thermal expansion coefficient matching, and better heat transfer can be achieved. The faceplate comprises a laser structure including an active gain layer and first and second mirrors on opposite sides of the active gain layer, and a transparent substrate thermal expansion matched to the laser structure and bonded to the laser structure. The laser structure and transparent substrate are bonded using diffusion bonding or sol-gel bonding to create the highly uniform bonding interface.

An epoxy-free faceplate for a laser-CRT comprising:
- a laser structure including an active gain layer, and first and second mirrors on opposite sides of said active gain layer;
- and
- a transparent substrate thermal expansion matched to said laser structure and bonded to said laser structure, such that a highly uniform interface is formed between said laser structure and said substrate.
An epoxy-free faceplate for a laser-CRT comprising:
- a laser structure including an active gain layer and first and second mirrors on opposite sides of said active gain layer;
- and
- a transparent substrate diffusion bonded to said laser structure, thereby providing a uniform interface between the laser structure and the substrate.
