Product Overview:

90 Amp CW and Pulsed OEM Laser Diode Driver Overview

The LDD-1125 is an advanced laser diode driver that contains a specialized current source able to precisely drive laser diodes in continuous, modulated, and pulsed modes or a mixed operation. They can be configured with optional laser power measurement circuitry (photodiode input). The LDD-1125-LPC can also be operated as a laser power controller.

The base model LDD-1125 can be connected in parallel to increase the available output current. The 90 Amp LDD-1125 model is comprised of three single laser diode drivers in parallel. Our Meerstetter support team will be happy to help you with the wiring and configuration of the devices.

Flexible Pulse Parameter Control

The core element of the LDD's internal current source is the generation of highly precise 333 ps timing PWM steps that result in high resolution and very low ripple current. The output is short-circuit safe and can be chopped for up to 40 kHz pulsed-mode operation. Driving low inductive loads and ultra-short fall and rise times are achievable.

Laser Diode Protection Features

For ultimate laser diode protection the supervision of critical system values is directly implemented in hardware. This results in very fast switch-off times (<8 μs) in case of limit value violation. The LDD-1125 also monitors laser diode temperature (NTC thermistor input). The LDD-1125 is fully digitally controlled; its firmware is upgradeable to offer various communication options and to meet specific customer requirements.
