1064nm, 120W Output, 400µm Multimode Fiber-Coupled Laser Diode in Turn-Key Control System

Product Overview:

Pre-Configured 1064nm, 60 Watt Turn-Key Laser Diode Source Overview

The LDX-1064NM-60W is a high power laser diode source with a pre-configured control system. These instruments are fully integrated turn-key fiber coupled source solutions. An integrated fiber-coupled single bar source is precisely controlled and delivers a high stability output. The current source, laser diode, temperature controller and cooling plate assembly are all integrated into a 19 inch rack-mount enclosure.

This all-inclusive high power systems includes a high power fiber coupled laser module installed and validated in the system. The module includes a thermistor and pilot laser. Controlling the laser is a high power laser diode current source and a 336 Watt cooling system. The cooling system is air-based (no cooling water necessary).

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.
