Product Overview:

976nm, 50 Watt Turn-Key Laser Diode Source Overview

The LDX-976NM-50W laser diode system is a high performance fully integrated turn-key instrument for R&D and manufacturing applications. It includes an integrated 976 nm high power fiber coupled laser manufactured by Lumics, a high power current source, TEC controller and a Peltier cooled laser mounting plate assembly. All of these components are integrated into a 19 inch wide, 2U high enclosure. All of the systems settings are pre-configured at the factory and the unit is calibrated with the integrated laser diode. Industry leading protection features ensure that the laser diode is protected at all times.

User has Complete Control of the 976nm Laser

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. Laser output power is set by adjusting the current level (ACC mode) or adjusting the laser power in watts using the automatic power (APC) control mode. The APC mode utilizes the laser diode's internal monitor photo-diode to feedback to the bias current source. The LDX systems can be controlled remotely by RS232 or optional USB interface, and the system ships with LabView drivers.

Factory-Configured Laser Diode Protection

The LDX-976NM-50W series instruments ship with pre-configured protection settings to make sure that the laser is run safely and operates within the specified maximum operating limits. These limits include the upper current limit and upper temperature limit. Additionally, a soft-start current ramp is set to 300 milliseconds to protect the laser from thermal shock when the bias current is applied. This soft-start ramp time can also be customer configured through the front panel or digital interface. These units also have clamping circuitry to protect the laser against power surges and ESD.

TEC Based Temperature Control System:

The system employs 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.
