In their corresponding folders, you will find the guidelines regarding the mounting of the motor in its housing.
1. In [the box CAD folder](AgitationBox) you can find the blueprints for a lighter version of the agitation box. It consists of four panels screwed together with M4 screws. One of the panel has a dent to let the motor power supply cable and the optical fiber enter & leave the box. A lid is also described, with a [3D printed handle](AgitationBox_V2\Handle), in order to dampen the noise.

> Tip: We placed an egg box foam under the box to protect the floor and improve the noise dampening.

9. The two red laser diodes are superimposed using perpendicular polarizations and a polarization beam splitter. In order to align the polarizations, place the polarization beam splitter in the right orientation (refer to the [Thorlabs page](https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=739) for the cube orientation). Then slightly unscrew the heat sink on the first red diode. If the diode beam is the transmitted one, then rotate the diode until its profile is horizontal (you need to be above the lasing threshold). Maximize the transmitted power through the beam splitter before fixing again the diode on the mount.
10. Next, repeat the procedure with the second laser diode, with this time a perpendicular orientation of the beam profile. (If the laser beam is the reflected beam, then the profile should be oriented vertically).
11. Finally, maximize the coupling of the red diodes in the optical fiber by beam walking them. Coupling can further be improved by also rotating the square optical fiber so that the long axis of the fiber profile is aligned with the long axis of the diode profiles.
12. The illumination on the microscope is described in the paper and might depends on the microscope itself.
12. Place the enclosure on top of the breadboard to protect the user and the optics.

- Always work with adequate laser light protection.
- The foam board used in the [enclosure](Laser_Engine\Enclosure) is a fire hazard when subjected to strong laser light. Make sure to place beam stops behind the dichroic mirrors and the polarization beam splitter so that no laser beam hits the foam board panels.
