Laser Diode Micro-Modules (LDMM’s) address the need for a simple, robust, reliable, and cost-effective platform on which to mount, provide heat sinking abilities, collimate, and power semiconductor laser diodes. The use of laser diodes in scores of applications has become ubiquitous, and our new products make mounting, collimating, heatsinking, and providing power leads for such applications easier than ever.


Product Description

The LDMM comprises an anodized aluminum body, a rear aluminum diode plate that is used to secure the diode into the body and provide heatsinking, and a square printed-circuit board that is mounted directly adjacent to the diode plate to which leads are soldered. The body contains a threaded cylindrical hole accessed from the front (output) face of the module, that is used to provide mounting for and the axial adjustment of the collimation lens. The LDMM also has two threaded mounting holes on the bottom face of the module for mounting on a heat sink, and four threaded mounting holes on the output face for the same purpose.

Our LDMM’s can be used for stand-alone applications, or can be easily integrated into customer devices. For example a stand along LDMM can be used in the laboratory to provide an alignment laser for a wide variety of applications and in the wavelength range from 375-2000 nm. Our modules may also be used as educational tools, to teach students about the use of laser diodes, how they are connected and driven electrically, how to collimate the diode output, and how to provide heatsinking. Modules can be provided that are eye-safe and CDRH compliant, making their use as educational tools easy. Commercial, military, and medical and bio-medical applications abound.

Additional Custom LDMM Info

Virtually any diode that is mounted in a 3.8, 5.6, or 9.0 mm TO can be mounted and collimated using our LDMM. We can provide any quantity of custom modules, collimated or uncollimated, to customers on a proprietary basis, using APS or customer-bought laser diodes. We will characterize any laser diode in our LDMM package without cost to any serious customer, at any wavelength from 375 to 2000 nm. At present, we limit our green output power levels to < 1000 mW due to low diode efficiency. We provide the complete assembly, wire pair pigtailing, and full testing of each LDMM.
