400W Laser Diode Thermoelectric Chiller

The LDX-36000 Series High Power Laser Diode Drivers
are a family of high performance current sources designed
specifically for controlling and testing high power laser diodes.
Over ten models offer maximum current ranges from 10 amps to
220 amps QCW and 125 amps CW with maximum compliancevoltages from 12V to 35V. Each instrument offers high setpoint
accuracy, low output noise with forward voltage and photodiodemeasurements in CW, QCW-Pulse and hard pulse operating
modes making these instruments ideal for precision, high power
laser diode testing.
Multiple laser diode protection features include adjustable
voltage and current limits, output shorting relays, slow turn on/
off circuits, fast error detection circuits, and transient protection
during power up and laser operation. A thermistor based
temperature monitor provides additional protection through a
programmable temperature limit which can be used to disable
the laser output when the limit is exceeded.
Designed for automated laser diode testing in CW or pulse
mode, these drivers combine precision control and measurement
and an IEEE488/GPIB interface with on-board data storage forhigh power laser diode characterization. For virtual instrument
programming, LabView instrument drivers are available free ofcharge and can be downloaded from the ILX website.

In keeping with our commitment to continuing improvement, ILX Lightwave reserves the right to change
specifications without notice or liability for such changes.

LDX
36000
SeriesHigh Power
Laser Diode
DriverHIGH POWER PRECISION LASERDIODE TESTING
Each LDX-36000 Series Laser Diode Driver was
designed as a current source specifically for highpower laser diodes. Ideal for R&D or manufacturing
testing, precision low noise current control with set point
accuracy of 0.1% of reading is delivered to the lasers,with four-wire voltage measurement and a photodiodemonitor with adjustable reverse bias for CW and QCW
LIV testing, laser qualification testing, or pulse testing.

A CHOICE OF LASER CURRENT CONTROL
MODES
Each LDX-36000 can be operated at full scale current
and voltage in CW or QCW mode saving time andreducing cost of test by eliminating multiple instruments
and test set-ups. Conduct CW L-I-V testing and pulse
testing of high power laser diodes all at the same test
station, without moving the laser or changing the output
cable. With the 36000’s there is no need for another
QCW instrument, simply change operating modes fromthe front panel or through the GPIB interface, set up thetest parameters and start testing quickly in either mode.
In QCW mode, the pulse output can be generated either
internally with programmable pulse width, duty cycleand frequency parameters or through an external pulse
trigger.
For some applications, long pulse widths are required
during testing. All 36000 models offer a “hard” pulse
mode where the pulse width can be adjusted from 1 ms
to 2 seconds with a duty cycle up to 90%.

of pulse parameters for maximum flexibility in varying
test applications. The pulsed output can be generated
in one of three modes; internal pulse, hard pulse, andtriggered pulse. If the LDX-36000 is being used indiode-pumped solid state laser and amplifier testing,programmable input and output trigger delays allow for
optimizing Q-switch timing and energy extraction without
the need for any external delay generators.

DESIGNED TO PROTECT HIGH POWER
LASER DIODES
Eliminate problematic current spiking common with
voltage sources. Each LDX-36000 Series Laser Diode
Driver was designed as a current source specifically forhigh power laser diodes. The drivers provide multiple
laser diode protection features such as current andvoltage limits, slow start turn-on, floating outputs, fasterror detection, and immunity to operational and powerline transients. Careful attention to design has resulted
in minimal overshoot in QCW mode or while rapidly
stepping current in CW mode at any output current
level. Transients from normal instrument operationsuch as output on/off have been thoroughly tested
and minimized as well as transients from inadvertent
instrument operation (such as mode switching).
In case of a device failure with multiple devices
connected in series, low overshoot and closed-loop
power supply control ensure the remaining devices
safety. A temperature monitor provides additional
protection with a programmable temperature limit which
disables the current source output in a limit condition.

Additionally, a unique power display mode allows laser
diode power to be set based on programmable slope
efficiency and threshold current parameters.

CW and QCW Operating Modes

PRECISION PULSE CONTROL FOR HIGH
POWER LASER TESTING
The LDX-36000 Series offer several QCW operating
modes delivering clean pulses with low overshoot andfast rise and fall times. Digital control of pulse width,
duty cycle and frequency provide quick and easy control

LDX-36000 Series instruments accept an external trigger
to synchronize the output pulse.

AUTOMATE HIGH POWER LASER TESTING
Remote instrument operation is available on all of the LDX36000 Series High Power Drivers through an IEEE488/
GPIB interface. All instrument controls and functions
are accessible through the interface for easy remote
programming and control in automated test systems where
repeatable and accurate test sequencing, measurements,
and data handling are required. Whether the applicationis data intensive L-I-V testing, pulsed control for thermal
characterization, or R&D evaluations, remote operation of
the LDX-36000’s saves time and ensures systematic datacollection and instrument operation.

output current setpoint, current and voltage limits andcalibration constants are easily selected and adjustedwith the rotary digital encoder. Each display is easily
configured to indicate laser parameters such as current,
voltage, power, and temperature with discrete control
push buttons located below each display. Systemerrors such as open circuits and current or voltage
limits are indicated with discrete LED’s with an error
code indicated on the appropriate seven-segment
LED display.

PRECISION L-I-V TESTINGSAVE AND RECALL INSTRUMENT
SETTINGS

Each LDX-36000 Series Laser Diode Driver was developed
specifically for precision L-I-V testing of high power laser
diodes with 0.1% set point accuracy, low noise and precision
forward voltage measurement capability in CW or QCW
pulsed modes. Additionally, the instrument can perform
power measurements through an independent photo-diodeinput calibrated with a user-programmable responsivity.
An adjustable 0 to -15V reverse bias ensures linear
measurements and fast conversion speed. Accurate forward
voltage measurements even with high current and longcable lengths are accomplished real time through a four wiremeasurement system. Reduce total system cost with thesehigh current drivers; there is no need for separate pulsed
sources, voltage measuring instruments, or low current
measuring instruments for high power L-I-V testing.

any time through simple front panel button presses orremotely through the GPIB interface. This saves time in
instrument re-configuration for different manufacturing
