Low-Noise Quantum Cascade Laser Driver Instrument
THE LOWEST-NOISE DRIVER NOW
AVAILABLE AS AN INSTRUMENT
These low noise QCL instruments have the lowest current
noise density of any commercially available. Powering yourQCL with this patented1 driver gives you narrow linewidth,stable center wavelength, and repeatable scans. This is theright instrument for lasers that require a high-precision andultra-low noise current source to measure concentrations
lower than ever before. The 500 mA QCL driver exhibits
noise performance of 0.4 A RMS to 100 kHz, and an
average current noise density of 1 nA / Hz—the lowest
available today.

ULTRA-NARROW QCL LINEWIDTH

In order to maintain their characteristically tight center
linewidths and minimize jitter, quantum cascade lasers must
be powered by drivers with exceptionally low current noisedensity. Our customers have reported achieving narrower
linewidths with our QCL drivers than any other they’ve used.

HIGHEST MODULATION BANDWIDTHThe high modulation bandwidth and fast rise-time maintains
modulation waveform integrity so you can shape the laser
output prole exactly as your application requires.

INTUITIVE USER INTERFACE AND
SUPERIOR SOFTWARE CONTROLWith Wavelength’s plug and play instrument, you have theability to quickly set the controls using either the instrument
touchscreen or remote control, and then easily monitor theresults.

PROTECT YOUR QCL INVESTMENT
All the essential control and monitor functions you expect ina Wavelength product are incorporated into this QCL driver,along with protection circuitry to safeguard your QCL fromminor power source faults, over-temperature conditions,and electrical faults.

APPLICATIONS
Due to their unique construction, QCLs operate with highpower in the near-IR through terahertz ranges. Thesewavelengths are particularly suited to detection of molecules
signicant to humans. Applications for the lower noise QCL
driver include: remote detection of explosive materials,
medical diagnosis using the breath, non-invasive glucose
testing, emissions monitoring, and pharmaceutical process
quality control. Additional applications include anesthesia
and hospital air quality monitoring, leak detection, andremote imaging.

ALLOW OR RESTRICT PERMISSIONSCONTROL THE INSTRUMENT VIAREMOTE COMPUTERThe QCL Laboratory Series instruments can be controlled
remotely from a computer using the LAB Quick Connect
Application software. Once the software is downloaded
and the instrument connected to the computer via a USB orEthernet cable, all operations can be performed remotely.

ADJUST, ENABLE, AND SCAN FROMTHE CONTROL SCREEN
Adjust Setpoint, Limit Current, Supply Voltage, Cable
Resistance, Turn On Delay, and complete a VI scan, all fromthe remote computer Control Screen.
Enable and disable current to the laser or turn the instrument
front panel on and off.

The LAB instrument allows two levels of permissions,
Normal User and Super User. The Super user has theability to modify any remote operation and to assign
permissions for Normal Users. Access to permissions
is password protected and the ability to access specicvariables or proles can also be allowed or denied. For
example, changing the current or voltage limits can berestricted while allowing setpoint changes.

SAVE AND RECALL SETTINGS
All of the values to operate the QCL laser can be enteredin a prole. Up to ten proles can be uniquely named andappear on the instrument even when disconnected fromthe remote computer.
