Product Overview:

915nm Laser Diode Source System Overview

The LDX-915NM-10W features a Lumentum 2-pin multimode pump laser diode source integrated in a precision control system. It is a pre-configured system which includes the fiber coupled L4 packaged laser, the controller, the mounting plate/heat sink and the interconnect cables. This fully configured system is optimized for driving and controlling high power single-emitter pump lasers. The mounting hole footprint pattern is pre-configured for the Lumentum L4 and L4i package style module. These systems are also available at 940nm and 975nm center wavelengths.

User has Complete Control of the 915nm Laser Diode


The user has complete control of the 10W laser diode through the front panel or through the rear panel RS232/USB. The user controls the bias current, temperature set-point, CW or modulated mode and all other key parameters. The front panel has an LCD display with a touch key-pad. The menu structure is simple to operate, and features a status menu with current and actual temperature for the default home page setting. These systems come with an RS-232 interface and can be ordered with an optional USB interface. LabView drivers are available free of charge charge.

Fully Configured Temperature Stabilized Mount and Heat Sink


These units have an high power TEC temperature controller with a full P.I.D. control loop to provide fast and temperature control of the source laser module. The laser diode is mounted on a 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.
