ILX Lightwave LDC-3700 Series User Manual

LDC-3700 Series Laser Diode Controller will be set to operate in constant P, mode, and the
PpD set point value will be in effect.
If this value is 0, the front panel Pm will display "-.-", and no Pm value can be calculated.
In local operation, the CALMD (CAL PD) value can be read by selecting the CAL PD
parameter and
visually reading the LASER display.
EXAMPLES
"LASER:CALMD?" -response: 0, means the LDC-3700 Series Laser Diode Controller is set
for operation in constant I, mode (if P mode is also selected).
"Las:Calmd?" -response:
1.1, means the LDC-3700 Series Laser Diode Controller is set for
operation
in constant PpD mode (if P mode is also selected) and the responsivity is set to
1.1 uA/mW. 1.1 uA of photodiode feedback current represents 1 mW of optical power.
Front Panel
The
LASer:CAL: command
path is used to get to the LDC-3700 Series Laser Diode Controller's laser
calibration commands.
In local operation, the LASER calibration mode is reached by pressing the (GPIB) LOCAL and (LASER
DISPLAY) I or I, switches at the same time.
The following commands may be reached directly from the LASer:CAL: command path.
Front Panel
The LASer:CAL:LDI command is used to enter the LASER current set point, measurement, and limit (in
low bandwidth mode) cabbration mode.
