75 Amp OEM CW Laser Diode Driver Overview

The latest generation LDD-1137 is an advanced performance laser diode driver. It is available in two models: a CW mode and a Pulsed mode model. New, high performance eGaN FETs enable lower noise, high resolution control and increased electrical efficiency. A new processing core enables a faster processor connection to the powerful FPGA, more interfaces, more precise timing, and additional functions, while still maintaining a 1.5 mA resolution and keeping a very low output ripple. Equipped with optional light measurement circuitry, the LDD-1137 can also be operated as a Laser Power Controller (LPC).

Low Noise Output and Industry Leading Laser Diode Protection

These modules are innovative current drivers that contain a proprietary current source able to precisely drive laser diodes in pulsed or CW mode. It can be equipped with an optional laser power measurement circuit / photo-diode input. The LDD-1137 also monitors laser diode temperature (NTC thermistor input). The LDD-1137 is fully digitally controlled; its firmware is upgradeable to offer various communication options and to meet specific customer requirements.

USB and RS485 Interfaces with Control Software

The included PC-Software (USB / RS485) facilitates configuration, control, and real-time monitoring of the LDD-1137. All device settings are saved in non-volatile memory and can be backed up and restored. For remote / OEM applications, the LDD-1137 may be fully controlled by a system bus that features RS485 communication, pulse, interlock and 6 reserve lines. The LDD-1137 is part of the LDD family of Meerstetter laser diode drivers, which are designed to operate alongside devices of the TEC family of Peltier controllers.
