Where to Buy Laser Diodes

Sheaumann Laser offers a wide range of laser diodes, ranging from low-power single-mode emitters to multimode high-power lasers. Many different packaging options (with free-space output or fiber-coupled) are available. Emission wavelengths range from 785 nm to 1064 nm.

Bright Solutions offers the BDL and BFD – fiber-coupled diode laser modules:

• up to 200 W cw (or 400 W quasi-cw) in a 200-μm core fiber
• flat top beam profile
• integrated TE cooler, current and temperature controller
• optional fiber sensor
• pulsed models are available

They are used e.g. for pumping of solid-state and fiber lasers, material processing or illumination.

TOPTICA offers a large variety of wavelength-selected single-mode laser diodes. Among more standard laser diodes you will also find "rarities", i.e. diodes with output wavelengths that only TOPTICA provides. The diodes can be purchased separately. In addition TOPTICA can integrate any diode from the stock lists into a tunable diode laser system: Fabry–Perot or AR-coated laser diodes may be integrated into a diode laser systems, DFB/DBR laser diodes into a DFB pro and tapered amplifier into an TA system.

Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet. In case you can still not match your wavelength of choice, contact TOPTICA – and chances are very high that we can provide it.

LD-PD offers a wide range of laser diodes based on a single heterojunction (SH), double heterojunction (DH) or quantum well (QW) gain medium. We also offer variants like Fabry–Pérot lasers and distributed feedback lasers, including single-frequency versions. Many lasers have a butterfly package with integrated thermoelectric cooler, while others have a TO package.
