Constant power controls
In constant power mode each laser has a field where the output power can be set. The power set point for each
laser controls the emission from the individual laser heads and not through the C-FLEX aperture. The expected
power out of the C-FLEX aperture can be found on the test protocol.
Cobolt 04-01, Cobolt 06-DPL and Cobolt 08-DPL laser power controls are connected to a calibrated internal
photodiode that delivers a real time power measurement and controls the drive current via a feedback loop.
Cobolt 06-MLD lasers display the power corresponding to a particular diode current from a calibrated look up
table.
Cobolt 08-NLDs and Cobolt 06- MLD’s are shipped in constant current mode to achieve optimum performance,
it is not recommended to run these products in constant power mode.
To read the power setting without the Cobolt Monitor software, use the command ‘p?’ . The output power of a
specific laser line can be set with the command ‘p X.X’ where X.X is the power in Watts (W) . For example, to set
an 08- DPL power to 25 mW the command is ‘p 0.025’. The maximum allowed power is set at the factory.
Constant current controls
The laser output power can also be controlled with the current setting in constant current mode. Cobolt 08-
NLDs and Cobolt 06- MLD’s are shipped in constant current mode to achieve optimum performance, it is not
recommended to run these products in constant power mode.
To read the current setting without the Cobolt Monitor software, use the laser specific command ‘i?’ . The drive
current, and therefore output power, of a specific laser line can be controlled by setting the current with the
com mand ‘slc XXXX’ where XXXX is the current in milliamperes (mA) . For example, to set the current to 2500
mA the command is ‘slc 2500’.
The emission from a specific laser line can be stopped by sending the command to set the current to zero. For
example, to set the current to 0 mA the command is ‘slc 0 ’.
The current control can be used to toggle the laser between different current settings with commands, such as
between the threshold current (low or no current) and the current setting that corresponds to the nominal
output power. This can be especially useful during alignment of the optical path. There are safety controls in
place to prevent the user from exceeding the safe maximum current for any given laser line.
