Product Overview:

60 Amp CW and Pulsed OEM Laser Diode Driver Overview

The LDD-1125 is an innovative laser diode driver that contains a specialized current source able to precision drive laser diodes in continuous / modulated and pulsed or mixed operation. Equipped with optional laser power measurement circuitry (photodiode input), the LDD-1125-LPC can also be operated as a Laser Power Controller.

The LDD-1125 can be connected in parallel, the 60 Amp LDD-1125 are two single laser diode drivers in parallel. Our Meerstetter support team will be happy to help you with the wiring and configuration of the devices.

Laser Diode Pulse Flexibility

Core element of the LDD's internal current source is the generation of highly precise 333 ps timing PWM steps that results 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, 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.
