Introduction
Thank you for choosing the ComboSource from Arroyo Instruments. The
ComboSource combines the features of our LaserSource and TECSource into
a single, powerful instrument. The ComboSource represents years of
experience in the field of current and temperature control.
With a large, crystal clear VFD display, both RS232 and USB computer
interfaces, and small footprint, the ComboSource will fit into almost any laser
diode control application. Unlike other controllers in its class, which use
inexpensive 7-segment displays, the ComboSource takes advantage of its large
VFD display to simultaneously show the set points and measurements.
The ComboSource also includes complete optical isolation of both modulation
and photodiode inputs. By isolating these inputs, it prevents unwanted ground
loop problems. No other laser diode driver in the industry has this feature. The
ComboSource also operates in constant voltage control mode, allowing you to
use it in precision voltage applications, such as EML devices, or for doing V-I
measurement graphs.
The user interface of the ComboSource is engineered to make using the
instrument straightforward. With its text-based menus, there is never any
confusion over which setting is being changed, and parameters are displayed in
clear English (no cryptic numbers or LEDs to decode).
The ComboSource offers all the features you would expect from a modern
precision laser controller, including:
Laser driver:
o 10ppm current stability
o 100mA to 4A current ranges
o High compliance versions for QCL applications
o Comprehensive laser protection circuitry, including hardware
voltage and current limits, and fast transient shutdown.
o External analog modulation
o Power mode control, both in photodiode current (AMC) or
computed photodiode power (APC) modes.
Temperature Controller:
o AutoTune for automatic PID parameter calculation
o 0.004°C temperature stability and 0.01°C set point resolution
o 60W (5A/12V) output power
Simultaneous display of set points and readings
