Parameters
Notes
Examples
An <nrf value> that represents the laser monitor photodiode power limit in mW.
When constant MDP mode is used, the output level is limited only by the LIM Ix value.
Exceeding the powere limit will either cause the output to shut off (default) or generate a
warning (see LAS:ENAB:OUTOFF command).
"LAS:LIM:MDP 10" -action: sets the laser output power limit to a value that corresponds
to producing 10.00 mW of photodiode feedback (optical) power.
"Las:Limit:MDp 5" -action: sets the laser output power limit to a value that corresponds to
producing 5.00 mW of photodiode feedback (optical) power.
LASer:LIMit:MDP?
FRONT PANEL
REMOTE
The LASer:LIMit:MDP? query returns the value of the laser monitor photodiode power
limit.

- where the response is the LASER power limit setting.
The (LASER) MDP limit is in effect for both laser output current ranges.
The MDP limit is not in effect when CALMD=0. In this case, the monitor current
measurement is not converted to power.
"LAS:LIM:MDP?" -response: 3.0, means the monitor photodiode power limit is set to
3.0 mW.
":LAS:Limit:MDP?" -response: 10.0, means the monitor photodiode power limit is set to
10.0 mW.
