Product Overview:
The LDC-3736 from ILX Lightwave was designed with multiple layers of laser protection developed specifically for expensive Quantum Cascade Lasers. It also provides high current output stability and precise temperature control to ensure that your laser's frequency is locked and that your data is accurate. A 4 Amp precision high stability current source is also capable of sourcing up to 18V to the QCL under test, while the ultra-stable temperature controller provides fast and efficient heat removal from the QCL.

An easy to use and intuitive front panel interface is complemented by standard GPIB and USB rear panel connections which are offered with LabView drivers.

Small drive current fluctuations due to noise and drift are amplifi d optically. Due to this, a controller with a low noise and stable output current is required to ensure stable optical output current. Since current noise scales with maximum current output, the LDC-3736 includes three current ranges: 1A, 2A, and 4A. This
flexibility allows users to select a range close to their maximum output to reduce current noise and provide future expansion when working with different lasers. This feature allows the LDC-3736 to deliver current stability as low as 20 ppmand <10µA to ensure stable operation in sensitive applications.
Careful attention to the design of the thermoelectric temperature controller allows high power operation
with low TEC current RMS noise. This reduces the chance for TEC noise coupling into the laser, which
could potentially cause unstable operation. ILX Lightwave’s internal testing and protection standards
ensure protection for lasers under abnormal operating conditions, such as intermittent contact or severe
power spikes. These standards have led to advanced protection features such as clamping current limits,
even under modulated conditions. In addition, exclusive braid-shielded cables have been specifically designed to suppress radiated noise and transients commonly found in laboratory or production environments. During AC power-up, careful turn-on sequencing and redundant output shorting circuits protect the laser from current transients.
