Laser Diode Standard Modules

Advanced Photonic Sciences is Now Offering Laser Diode Standard Modules

Introduction:

Recently, Advanced Photonic Sciences (APS) introduced a new product line of Laser Diode Micro-Modules (LDMM’s) that address the need for a simple, robust, reliable, and cost-effective platform on which to mount, provide heat sinking for, collimate, and power semiconductor laser diodes. Now, APS is also offering the same diode-laser mounting convenience in a configuration that incorporates a location for mounting an anamorphic prism pair for laser beam circularization and an optional adapter plate that includes a thermoelectric cooler and thermistor sensor for active temperature stabilization, named Laser Diode Standard Modules (LDSM).

Laser Diode Standard Module (LDSM) with Anamorphic Prism Pair

The LDSM comprises an anodized aluminum body machined out of a solid block, a rear aluminum diode plate that is used to secure the laser diode into the body and provide heat sinking, 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 LDSM also has two thru holes for mounting on a passive or actively temperature cooled heat sink. The LDSM has the following important attributes:

  • Excellent Heat Removal Properties
  • Inexpensive
  • Easy Solder Connection of Power Wires
  • Simple Mounting
  • Accommodates Any M9x0.5 Collimation Lens

Our LDSM’s can be used for stand-alone applications, or can be easily integrated into customer devices. For example a stand along LDSM 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. The following applications are a natural fit for our LDSM devices:

LDSM Applications

  • Optical Pumping of Solid-State Lasers

Custom LDSM Offerings:

Virtually any diode that is mounted in a 3.8, 5.6, or 9.0 mm TO can can be mounted and collimated using our LDSM. 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 LDSM 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 LDSM.
