Front Panel Operation

This section describes the fundamentals of operation for the LDX-36000 Series
High Power Laser Current Source. The order of descriptions will follow the normal
progression of how one would typically configure the instrument for use for the
first time. Each operational mode, CW and QCW will be described in its own
section.

The Adjust Knob

The Adjust knob shown in Figure 3.4 is
used to adjust and set the various
operational parameters of the
instrument. Depending on the
parameter being adjusted, changes will
either occur immediately upon rotation
of the knob, or after either the Adjust or
Set button is pressed.

Display 1

While adjusting parameters for optical power setpoint, photodiode responsivity,
and thermistor calibration constants, Display 1 will show labels identifying each
parameter while the value will be shown in Display 2. This will be described in
more detail in the sections that follow.

Figure 3.5 Adjust Knob

The left-hand display, labeled Display
1, shown in Figure 3.5, is used to show
the laser control parameters of laser
drive current (A), laser forward voltage
(V), (peak) optical power setpoint (W),
and measured optical power from an
external photodiode (W PD). In
addition, limits for laser current and
compliance voltage may be displayed
here.
