Please consider for your new projects our LDD-1137 with similar or better parameters.

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. The free of charge PC-Software enables an easy and quick integration into your system. 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 work as CW Laser diode driver or Laser diode pulse driver. 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.
