LOWEST-NOISE DRIVER AVAILABLE
The QCL OEM Series drivers use patented
1
circuitry to
produce the lowest current noise density of any commercially
available QCL driver. The 500 mA QCL driver exhibits noise
performance of 0.4 μA RMS to 100 kHz, and average current
noise density of 1 nA / √Hz—the lowest available.
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 noise
density. Our customers have reported achieving narrower
linewidths with these drivers than any other they’ve used.

Battelle Memorial Institute.
APPLICATIONS
The QCL Series drivers are used in trace element detection
systems, both laboratory-based and field-deployed.
This driver is well suited to applications requiring fast
measurement times and ultra high sensitivity.
REVERSE POLARITY AVAILABLE
Often, with epi-down configurations of a QCL, the exit
lead is attached to the case and it is desirable to ground
it. Now, the reverse polarity driver, a current source, is
also available in the OEM package. See QCL OEM(+).
PROTECT YOUR QCL INVESTMENT
All the essential control and monitor functions you expect in
a Wavelength laser driver are incorporated into this driver,
along with protection circuitry to safeguard your QCL from
minor power source faults, over-temperature conditions,
and electrical faults.
