LDD-1301, the first Laser Diode Driver from Meerstetter Engineering optimized for CW. With a newly developed Power Stage, new eGaN FETs and processor. Still with the proven and stable MeCom interface protocol and free of charge PC-Software for easy integration into your system.
If you are interested in the LPC (Laser Power Control) option, please do not hesitate to contact us.

Detailed Description

The LDD-1301 is a Laser diode driver optimized to drive CW diodes. eGaN FETs enable fast driving and high efficiency.

A new processor allows more interfaces, more precise timing, and many more additional features, while maintaining the 1.8 mA resolution at much higher current and very low ripple.

Our Laser Diode Drivers offer various safety features, including an input for Laser diode temperature monitoring. They are fully digitally controlled. The firmware is upgradeable, offering various communication options and allowing specific customer requirements to be met.

Equipped with optional light measurement circuitry, the LDD-1301-LPC can also be operated as a Laser Power Controller (LPC).
