New product, complete redesign and improvement, leveraging new technological advances and several years of experience with the previous Laser diode driver generation. Furthermore, with the proven and stable MeCom protocol and our free PC software, for an easy integration into your system.
The LDD-1137 is a specialized laser diode driver able to work as CW Laser diode driver. New emerging technologies like eGaN FETs enable better efficiency. A new processing core enables a faster processor connection to the powerful FPGA, more interfaces, additional functions and much more, while still maintaining a 1.5 mA resolution with much higher current and keeping a very low output ripple.
This high power Laser diode driver is our most powerful device. As it has a max output of about 4900 W, it can be used as a diode driver, as well as a Laser driver. Equipped with optional light measurement circuitry, the LDD-1137-LPC can also be operated as a Laser Power Controller (LPC; available 2024).
The LDD-1137 offers various safety features, including an input for Laser diode temperature monitoring. They are fully digitally controlled and the firmware is upgradeable to offer various communication options and to meet specific customer requirements.
