Detailed Description
The LDD-1125 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 2 mA resolution and very low ripple.
Equipped with optional light measurement circuitry, the LDD-1125-HV-LPC can also be operated as a Laser Power Controller (LPC).
It is possible to connect the LDD-1125 in parallel to obtain n * 30 A maximum output current. n is a natural number. If you have any questions concerning this option, our support team will be happy to help you.
All LDD-1125s 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.
