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.


LD2TC5 LAB and LD5TC10 LAB Integrated Laser & Temperature Control Instruments.


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

LDxCHA Series

The LDxCHA product family has current levels from 2.5 A up to 15 A. The following models are available: LD2.5CHA (2.5A), LD5CHA (5A), LD10ACH (10A), LD15CHA (15).

LDD Series

The low noise LDD Series 8-pin DIP drivers with excellent current stability in constant current mode are ideal for laser spectroscopy, electro-optical systems, and contamination control devices.

LDTC Series

The LDTC Laser Diode Driver and Temperature Controller combines Wavelength’s proprietary FL500 and highly stable WTC3243 in one compact module.

LDTC 2-2 Series

The LDTC2/2 includes both a Laser Diode Driver and a Temperature Controller that each drive up to 2.2 Amps ans is available in either chassis or open frame format.

MPL Series

The MPL Series are very low noise laser diode drivers. They 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.


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.
