Optical output
24
Output fiber The output fiber is a non-linear crystal fiber with a 0.20 numerical aperture
1
The
fiber is terminated with either an FC/PC connector, an FC/APC connector, or a
collimator unit. Note that the fiber is sheathed in an armored jacket.
FC Connector The optical output of both the S024-010-000 and S024-010-010 lasers are
equipped with either an FC/PC or FC/APC connector at the end of a standard
plastic-sheathed optical fiber cord. Either connector provide a convenient means
of terminating the fiber and allow the use of standard receptacles or holders to
launch the light through free space into other optical components or equipment.
Note: A black fiber boot indicates an FC/PC connector and a green fiber boot in-
dicates an FC/APC connector.
Collimator The optical output of the S024-010-020 laser is equipped with a collimator at the
end of an armored cable (see Figure 4). A collimated beam exits the collimator
from a tube within a steel barrel that can be inserted into a receptacle of a target
optical device such as for example, a SuperK accessory or an optical power
meter – see “Collimator installation” on page 79.

Caution: Avoid scratching the collimator as it may prevent it fitting properly into
an optical input receptacle.
Note: It is recommended to fix the collimator using plastic screws instead of metal
screws to minimize scratches or other damage to it.
Collimator beam
properties
Within the collimator, an achromatic lens collimates the output beam to maximize
and subsequent coupling. However, using a single lens prevents the
simultaneous maximum coupling efficiency across all wavelengths of the beam.
The laser and collimator are designed so that the coupling is optimized for
maximum average coupling across the visible spectrum. This results in the beam
being slightly wider for infrared wavelengths when compared to the visible
