Abstract:
An endbell assembly operatively associated with a laser body includes a metal endbell component sealed to a crystalline endbell component which terminates with a crystalline optical component. The crystalline endbell and crystalline optical component are hermetically sealed without using a frit. This is achieved by polishing and a modified optical contacting technique whereby the optical component and crystalline endbell component are polished to a flatness of about 1/2 wavelength of light, placed in a contacting position and then thermally cycled at a temperature of about 400. degree. -500. degree. C. for about 1 to 10 hours, forming a substantially uniform unitary body. This seal is mechanically strong and minimizes the introduction of contaminants into the endbell assembly. In one embodiment, the crystalline endbell component is metallized and braze-sealed to the metal endbell component. In another embodiment, the two endbell components are hermetically sealed by modified optical contact and thermal cycling.
