New product, complete redesign and improvement, leveraging new technological advances and several years of experience with the previous LDD generation. A new, much faster processing core enables better timing, faster pulses, faster rise/fall times, while still using the proven and stable ME-COM interface protocol. Together with the free PC software a quick and easy to integrate solution for your system.
The LDD-1137 is a specialized Laser diode driver able to work as CW Laser diode drive or Laser diode pulse driver. New emerging technologies like eGaN FETs enable faster pulses, improved wave forms and better efficiency. A new processing core enables a faster processor connection to the powerful FPGA, more interfaces, more precise timing, 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 3500 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 2023).
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.
