•
Power mode – the power out of the fiber laser is held at a fixed level.
The mode set, depends on both the variant and the application.
Table 2
lists the
characteristics of the modes for each of the laser variants.
Table 2 Characteristics of power modes
Note: Variants that support both modes are configured from the factory to operate in
Power mode by default.
Note: To set the operating mode, see
“Power /current mode” on page 53
.
Trigger
A trigger logic input or output pin (see
Table 18
) is available on the Modulation
connector. The trigger pins can be used for two purposes:
•
To apply (input) a logic signal that initiates laser emission (A logic high
initiates emission.)
•
To output a logic signal that indicates laser emission. (Active high is output.)
For more information on connecting the trigger, see
“Connecting the trigger input or
output” on page 94
.
High temperature
shutdown
To prevent thermal run-away when the laser temperature exceeds 65 °C, the
emission is automatically turned off. The high temperature shutdown feature uses the
thermal control function inside the laser to turn off the emission.
Note: The laser remains ON and has communications enabled, only the emission is
turned off by the feature.
Power verification
This feature internally monitors the output power level from the fiber stage. If power
drops below a predefined level in relation to the measured pump current, laser
emission is automatically shut off.
Note: The slope of power versus pomp current is different for each individual laser
due to variations in their emission efficiency.
The feature prevents for example, the output power reaching its maximum value if
feedback disappears (unexpectedly) to the internal output power control function.
