Chapter 5 System Setup
Throughout the setup various hex keys are required to mount components. To remove or clamp cage system
components generally a 0.05" or 1.3 mm hex key can be used. During the alignment of the vertical segment the
upper dichroic needs to be removed (see step 4). For this a 1/16" or 1.5 mm hex key can be used.
Step 1: Laser Segment (OTKB-1)
Even though the description below will give a quick summary on how to use the laser diode driver (CLD1015), we
highly recommend that the user reads the laser control manual.
CAUTION
! !
Laser diode is highly sensitive to electromagnetic discharge. Make sure to wear ESD protection at
all times when handling the diode.
Remove the lid from the laser diode controller and mount the laser diode as shown in Figure 1. Make sure the laser
diode orientation corresponds to a type 1 pump diode. Use the mounting screws provided with the controller to
attach the diode to the controller mount. This will ensure a good thermal contact between laser and mount.
We recommend coiling the fiber so that it can be placed inside the controller. Do not bend the fiber too tightly, this
might break the fiber. Make sure to clean the fiber before connecting. Plug the FC/APC fiber connector into the feed
through receptacle on the rear side of the controller. Note that the receptacle may be on the opposite side from the
picture below. Make sure that you rotate the fiber connector until the key on the connector snaps into the groove
on the receptacle. Then use the locking mechanism to screw the connector onto the receptacle.
Connect the patch cable (P3-980A-FC-1) on the outside of the back of the controller. The other end of the patch
cable plugs into the collimator on the beam expander segment (see step 2).

Take the laser collimator (Thorlabs part TC06PAC-980) and connect it to the adapter (Thorlabs part AD12F) as
shown in Figure 1 (right side).
The laser controller (Thorlabs part CLD1015) requires settings as shown in Figure 2 and Figure 3.
