The laser has a closed loop interlock (RJ-11 port).
Fiber coupled collimator.
Implementation at S20
Laser enclosure as at B40, with shutter.
...
Divergence needs to be adjusted to match main laser (find good procedure to do this).

Finding a spot for the laser: here a photo before closing up the enclosure (Dec 2021):
Implementation at B40
Laser enclosure as at B40, with a 2" Macor shutter.
To activate the laser one has to push a button on the front panel.
...
Some lens tube is used to restrict access to the fiber connectors and to protect the fiber from mechanical damage.
In S20, we enclosed the full laser with the reasoning that we will keep the laser on for extended periods of time, so we will not have to access the button.
