The LASer:MDP? query returns the value of the laser photodetector power measurement, in mW.
Notes The response is in mW. The response is valid, even when the unit is not in constant P mode.
This measurement is updated approximately once every 600 msec.
Examples "Las:Mode:MDP; Las:Calmd 460; Las:MDp?" −response: 100.0, means 100 mW of photodetector
power. This feedback is controlling the laser current output.
"LAS:MODE:IHBW; LAS:MDP?" −response: 20.0, means 20 mW of photodetector power, but pho−
todiode monitor current is not controlling the laser output current.
The LASer:MODE? query returns the selected laser control mode.
Notes I
HBW
mode is the same as I mode (low bandwidth), except that the output low bandpass filter is dis−
abled in I
HBW
mode.
Examples "LAS:MODE?" −response: ILBW, means that constant I (current) mode is in effect for the laser
output.
":Las:Mode?" −response: MDP, means that constant P (power) mode is in effect for the laser output,
and CALMD > 0.
"Las:Mode?" −response: MDI, means that constant P (power) mode is in effect for the laser output,
"Laser:MODE?" −response: IHBW, means that constant I
HBW
(current, high bandwidth) mode is in
effect for the laser output.
The LASer:MODE:IHBW command selects laser high bandwidth constant current mode.
Parameters None.
Notes This mode of operation is constant I mode with the output lowpass filter disabled.
Examples "LAS:Mode:Ihbw" −action: enables the laser high bandwidth constant current mode.
The LASer:MODE:ILBW command selects laser constant current mode.
Parameters None.
Notes Constant I mode (low bandwidth) enables the output low bandpass filter.
Examples "LAS:MODE:ILBW" −action: sets the laser output for constant I mode (low bandwidth).
