Unpacking The Laser System
The Northrop Grumman Iklwa laser was carefully packed for shipment. If the carton
appears to have been damaged in transit, have the shipper’s agent present when the laser
is unpacked.
Inspect the unit for dents, scratches, or other evidence of damage as it is unpacked. If
damage is discovered, immediately file a claim against the carrier and notify the Northrop
Grumman representative. Northrop Grumman will arrange for repair without waiting for
settlement of the claim.
Keep the shipping container. If a damage claim is filed, the container may be needed to
demonstrate that the damage occurred as a result of shipping. If the unit needs to be
returned for service, the specially designed carton assures adequate protection.
Laser Head Setup
The laser head should be mounted on an optical table or equivalent strong flat surface.
Three mounting holes are provided to secure the laser. The laser should be installed in a
clean environment.
A power meter, with the ability to handle a minimum of 30 W, should be installed
approximately 1.5 feet away from the laser in the direction of the laser output beam. To
protect the power meter, a negative lens (f=-100 mm) with an anti-reflective (AR) coating
at 532 nm should be installed in front of the power meter as shown in
Figure 4-1
below.
If a negative lens is not available, the power meter should be at least 2 m away from the
laser so that the beam size is larger and the power density is below the damage threshold
of the power meter. A pulse detector should be positioned as shown in
Figure 4-1
to
verify the pulse characteristics of the laser.
