The LDD-1124 is a specialized laser diode driver able to precision-drive laser diodes in continuous and pulsed operation. Core element of the LDD's internal current source is the generation of highly precise 333 ps timing steps that results in 30 μA resolution and very low ripple.

Equipped with optional light measurement circuitry, the LDD-1124-SV-LPC can also be operated as a Laser Power Controller (LPC). 

All LDD-1124s offer various safety features, including an input for laser diode temperature monitoring. They are fully digitally controlled; their firmware is upgradeable to offer various communication options and to meet specific customer requirements.
