Features And Benefits

These Nd:YAG laser output couplers are fabricated from UV fused silica substrates with excellent thermal performance and laser-grade surface specifications. Coating Technology: Electron beam multilayer dielectric; Adhesion and Durability: Per MIL-C-675A. Insoluble in lab solvents

Application

The laser output coupler transmits a portion of the circulating power within the cavity for generating useful output from the laser. The output coupler transmission is usually chosen to maximize the achieved output power, although its optimum may be lower or higher if there are other design purposes.
