Laser Diode Drivers

Ultra-stable, high precision quantum cascade laser drivers and laser diode drivers, in different formats, are available for a wide range of applications such as biomedical, imaging, spectroscopy, remote sensing, military, aerospace, communications, material processing, environmental and manufacturing control. Laser Diode Safety is paramount and protection is built into every Wavelength Electronics module.


A low noise, minature PCB mount 500mA current source .The FL500 is ideal for driving low power laser diodes where low noise is critical


The WLD3343 is a general purpose laser diode driver that maintains precision laser diode current or stable photodiode current using electronics that are compatible with any laser diode type.


The low noise LDD200 Series 8-pin DIP drivers offer excellent current stability in constant current mode or < 0.02% power stability in constant power mode.

MPL Series

The MPL250 is a very low noise laser diode driver. It operate from +12 to +15 V and is very easy to set up for any laser diode /photodiode configuration.

PLD Series

The PLD Series Laser Diode Drivers deliver the reliable performance in a compact and easy-to-integrate package. Versions are available with outputs are available from 200mA to 12.5 Amps.
