Gravitational wave detector mirror suspensions. (a) GEO600 triple suspension. (b) SOLIDWORKS rendering of an Advanced LIGO quadruple suspension.
Diagram showing the profile of one end of a dumbbell shaped fiber.
Power stabilization system. A small percentage of the laser power is picked off using a ZnSe Brewster window and measured using a photodiode. A graphite beam block is used to remove unwanted reflections.
SOLIDWORKS rendering of the fiber pulling machine in cylindrical fiber configuration. The functions of all parts are described in the text.
Rendered drawing of the laser beam delivery for cylindrical fiber production.
The 3 mm diameter cylindrical fused silica stock being heated by the CO laser as the fiber is pulled.
Rectangular cross-section fiber pulling machine. Ribbons are pulled from rectangular silica slides. The laser is dithered across the surface using a mirror galvanometer seen here at the front right hand side.
Photograph of a ribbon being pulled. The heating zone and stock material are enclosed in a steel heat shield to minimize heat loss from the edges.
The welding system consists of a CO laser delivered through an articulated arm, ZnSe output telescope, and a pair of mirror galvanometers.
A pair of computer controlled mirror galvanometers are used to move the laser over the weld region.
