Troubleshooting
In the unlikely case of a problem occurring, use the table below to help identify the error. Some faults can be fixed
remotely. Back reflections into the cavity can cause instability of operation. Isolators are available as an option. In
case of a sudden voltage drop the laser will turn itself off and restart. If it is in CDRH configuration it will require that
the key is turned on again. Contact Cobolt support or your local representative to identify corrective action.

04-01 laser systems. Cobolt provides a
warranty of 24 months or 5000 hours after delivery on the Cobolt Calyps0
™
04-01 laser systems. The warranty on the
fiber pigtailed (04-03) option is 12 months on faulty workmanship (24 months on the laser itself).
The laser systems are designed for modular repair or replacement in the event that the laser head or Controller
malfunctions. Warranty is invalid if the laser system is operated outside of the specific limits and conditions as outlined
in this document. The Cobolt lasers are contained in sealed enclosures and should not be opened for any reason.
Disassembly of any part of the system (including the cable) means the system no longer complies with the EMC
standards will void the warranty. All laser parameters are set at the factory, and there are no adjustments required.
Maintenance is limited to wiping dirt off the enclosures and cleaning the aperture.
Service
Due to accuracy tolerances, calibration differences and allowed power drift there may be discrepancies between the
Cobolt measurement of the optical output power and the customer measurement equipment. If the output power
deviates from the reported value please contact your local Cobolt representative for an online re-calibration. If the
laser does not function, do not attempt to open any of the units, or the warranty will be voided. Contact your local
Cobolt representative for consultancy and to request an RMA number (see back cover for contact information). If an
RMA number us issued and the laser needs to be shipped back to Cobolt or your local representative, please pack the
complete system for shipment using the original package or equivalent. Ensure the unit is free from thermal paste
before packing. The warranty covers repair or replacing the unit at the option of Cobolt.
