Quantum Composers Jewel Laser Operating Manual - Trouble-Shooting
Page 30 Jewel Manual v1.6 | Quantum Composers
The JEWEL LASER control electronics are designed to control the laser and warn the user of
problems that may occur. The microprocessor-based system monitors the laser system and
automatically shuts down if a fault occurs. Software limits have been factory selected to protect
the laser system against electrical and optical damage.
NO LASER OUTPUT
1. Check Fault and Interlock Conditions: Query status information using commands listed in
the command set. Refer to status to determine if a fault or interlock conditions exists.
2. Check Cables: With the main power OFF and unplugged, check all electrical connections
between the Laser Optics Assembly and the Laser Power Supply. Make sure all
connections are secured. If any of the cables are not installed properly, the system will not
function.
3. Check Shutter Position: The shutter is manually controlled and is located on the side of the
laser head. The laser will fire only when the shutter arm is in the open position.
4. Check Energy Setting: Refer to the data parameters supplied in the Data Summary Sheet
and make sure the parameters are not set below the lasing threshold. Correct if necessary.
5. Check Q-Switch Settings: Verify that the Q-Switch is enabled.
6. Check Diode and Qswitch triggers. Ensure they are correct for internal triggering or
external triggering.
ENERGY IS LOW
1. Resonator Misaligned: If beam quality has degraded, it may suggest that the resonator
needs realignment. Contact Quantum Composers for more details.
2. Incorrect Qswitch delay
– Qswitch delay typically matches the Diode Pulse Width. Correct
value if necessary.
Contact the Quantum Composers for any repair actions necessary beyond those described in this
manual. Attempts to adjust, repair or replace any portion of the laser system may cause
additional problems and void the warranty.
