LDMProduct Features
Simple and easy socket mountingfor HHL, TO-3 and other high power
laser diode packages
Unobstructed access to the frontof the laser diode package
Conveniently mounts to an
optical table
Water-cooled riser for optimum
heat dissipation
Compatible with ILX Lightwave
current sources and temperature
controllers

The LDM-4442 solves the fixturing and heat dissipation
problems associated with operating higher power laser
diodes.
This laboratory-quality laser diode mount has the ability todissipate up to 18 W of heat generated by a laser diode and its
internal thermoelectric modules.
The laser mounting plates, which attach quickly and easily tothe riser, are equipped to handle the most popular laser diodepackages. The front of the laser diode is easily accessible toprovide operational flexibility in a host of applications.

Interchangeable Laser
Mounting Plates
The LDM-4442 consists of an extruded heatsink, detachable base and water-cooled riser.
Interchangeable mounting plates, each designed toaccept a high-power laser package, are offered forversatile operation. A small circuit board, containing
the appropriate electrical socket, is attached to thereverse side of each laser mounting plate, allowing
for quick attachment of the laser diode.

on one end with standard D-subminiature connectors.
The other ends are prepared for easy termination
into the provided female connector. This allows easyinterface with the male connector affixed to the laser
mounting plate circuit board.

Conveniently Mounts to Standard
Optical Tables
The LDM-4442 can be attached directly to astandard (1/4 - 20 on 1” centers) optical table andconveniently aligns the laser diode at a 4” optical line
height. The laser package is electrically isolated fromthe table to prevent damaging the laser diode.

Interface with Any ILX Sourceor Controller
Each mounting plate kit comes with the cables
needed to interface to any ILX Lightwave current
source or temperature controller. The cables are fixedSpecifications
