Product Overview:

Pre-Configured 808nm, 50 Watt Turn-Key Laser Diode Source Overview

The LDX808-50W series instruments are high power laser diode source and control systems which are fully integrated turn-key bench top or rack mount source solutions. An integrated 50 Watt 808nm fiber coupled module from DILAS (also available with LUMICS source) is precisely controlled and delivers a high stability output.

This all-inclusive high power system includes a fiber coupled laser diode module, precision high power laser diode current source, 336 watt temperature controller and TEC / Peltier cooled laser mounting plate assembly, all integrated into a 19 inch rack-mount enclosure.

High Power Laser Diode Source Protection

High power laser diode protection features include a factory pre-set current limit, slow start current ramp to the user specified set point, factory pre-set temperature limits and clamping circuitry to protect the laser against power surges. The factory set default maximum current level is set during the calibration process to ensure the laser is not over-driven and damaged. The temperature limits are determined during calibration and are also factory set within a safe operating range to protect the laser against over-heating.

User Set Soft-Start Current Ramp:

In addition to the current the temperature limit protection settings, the user has the option of setting the soft-start current ramp time from 300 milliseconds up to 10 seconds. The system is set to a 300 millisecond ramp as the default mode for shipment. This user adjustable current ramp allows you to customize the "power on" sequence of the source for your specific application.

Air-Cooled Thermal Control System

These units have an integrated high power TEC temperature controller with a full P.I.D. control loop to deliver fast and efficient heat removal from the source laser module. The laser diode is mounted on a Peltier / TEC cooled, nickel plated copper mounting plate. The mounting plate offers very high surface finish and flatness for low thermal impedance. The cooled mounting plate for the laser is attached to a fan cooled air duct to remove the waste heat and keep the laser temperature stable.

User Controls

Users have full control of the fiber coupled laser module power through a touch-key front panel menu and LCD display or through the digital interface. You control the high power laser diode amplitude by adjusting the current level or adjusting the laser in automatic power (APC) control mode (Watts of optical power) based on the internal monitor photodiode feedback to the bias current and temperature controller.

These systems can be controlled remotely by the standard RS232 interface, or by the optional USB interface. They ship with LabView drivers and a terminal control software programming suite.
