Product Overview:

14 Amp Laser Diode Control Electronics for High Power Pumps

This high power control solution is an all-inclusive system for controlling high power single emitter pump laser diodes. It is optimized for 808nm ~ 980nm multimode fiber coupled pumps from companies such as Lumentum, Lumics and II-VI laser enterprise. This system includes a precision current source, a full PID temperature controller, an actively cooled heat sink and all required cables. The current source offers industry leading protection for your laser diode. The heat sink and TEC cooled mounting plate offer a high performance pre-configured mounting solution. The LDC-500X is an affordable, high performance solution for safely powering your laser and running at a stable temperature in laboratory environments. Standard mounting hole footprint patterns are available for many different module types. Refer to the specification table for common package type configurations. Or send us the data sheet for your laser and we will customize the mounting hole pattern on request.

Flexible Modulation, Internal Function Generator & QCW Pulse Modes:

In addition to CW (continuous wave) mode of operation, the 500X system includes flexible modulation capabilities and a slow pulse (QCW) mode. The rear panel of the controller has a BNC input for an analog or TTL digital modulation input with a 10K input impedance. The controller has an internal function generator which can be used to set the modulation signal or the quasi-CW pulses with a time base accuracy of 1.0%. In QCW mode, the user can also set the 20μs to CW pulses from a remote TTL signal source.

User Interface:

These systems come with a standard RS-232 interface and can be ordered with an optional USB interface. LabView drivers are available at no charge. A LabView GUI makes set-up and control of the system fast and simple. The user also has complete control through an intuitive front panel menu / LCD display with a key pad.
