IMPROVEMENTS IN OR RELATING TO SOLID-STATE LASERS

摘要

A method for assembling an optically pumped solid-state laser having an extended cavity is disclosed. The method comprises the steps of providing a casing (12, 13, 14, 202), mounting a TEC (16) and a base plate (17, 201) in the casing, and mounting a plurality of laser components (205-215) on the base plate using a UV and heat curing adhesive. Once the laser components are correctly positioned and aligned on the base plate, the adhesive is pre-cured using UV radiation. Final curing of the adhesive is obtained by subjecting the entire laser package to an ambient temperature of at least 100 °C. The base plate is preferably selected to have a CTE similar to that of the laser components in order to facilitate the high temperature curing. A preferred material for the base plate is AISiC.
