Precision driver for CW, QCW and pulsed operation, with internal signal generators for modulation and pulse. High efficiency and full digital control. Can also be used as a digitally controlled power supply. High-current variant of the LDD-1121, optionally with Laser Power Control (LPC). If you are interested in the LPC option, please do not hesitate to contact us.

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. Typical applications for the LDD-1125 are diode pumped solid state laser (DPSS, DPSSL) and Lidar.

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.
