Welcome to Thorlabs; below you will find links to light emitters, sources, and controllers, a subset of our entire line of photonics products. Our light sources are conveniently separated into coherent and incoherent sources. The coherent source category includes laser diodes, laser diode modules, tunable lasers, HeNe lasers, and femtosecond lasers, while the incoherent source link brings you to a selection of LEDs, white light, and broadband SLD sources. The Quantum Electronics category includes optical amplifiers, modulators, and gain elements that are frequently used in research and OEM applications. All of our light sources and optical amplifiers are supported by an extensive line of mounts, sockets, TEC controllers, and current controllers.

Premium Microwave Cables And Adapters
-
Thorlabs' Microwave Cables and Adapter Cables are flexible, high-performance, coaxial cable assemblies designed for use out to 50 GHz, depending on connector type (see the image to the right). The design gives these cables flexibility while maintaining optimal performance. They exhibit low VSWRs (Voltage Standing Wave Ratios) over the usable frequency range, as well as low insertion losses (see the Specs tab). These cables are each tested to ensure performance.

2-Wavelength, Polarization-Maintaining WDMs
-
Thorlabs' Fused Polarization Maintaining (PM) Wavelength Division Multiplexers (WDMs) combine two wavelengths of light in PM fiber while maintaining the polarization of the incident light. These WDMs are reversible; they can also be used to split two discrete wavelengths entering the common port into two separate output ports. They are not designed to split the output from a broadband source. PM WDMs are often used for pump / signal applications that incorporate erbium-doped or ytterbium-doped fiber amplifiers. They can be readily customized for a wide variety of applications, enabling rapid design cycles and new project builds. For custom requests, please contact Tech Support.

1.533 Μm Frequency-Locked Laser
-
Thorlabs' LLD1530 Frequency-Locked Laser is a narrow linewidth, DFB-laser-diode-based, turnkey system with a vacuum emission wavelength of 1532.8323 nm and a high SMSR of at least 35 dB. The laser frequency is actively stabilized to a National Institute of Standards and Technology (NIST)-traceable molecular transition of acetylene and has an absolute accuracy at start-up that is better than ±25 MHz. The emission frequency immediately after start-up is then maintained with a ±25 MHz stability, providing an overall frequency accuracy of ±50 MHz. The LLD1530 is an accurate frequency reference designed to provide low-noise laser emission with excellent frequency stability, accuracy, and precision immediately at start-up. This source is ideal for use in demanding FTIR instrumentation, instrument calibration, gas sensing, and coherent telecommunications applications.

Fiber Optomechanics
-
The versatile FiberBench product line includes Single and Multi-Axis FiberBenches as well as a wide variety of compatible components ranging from beamsplitter modules to wave plate units. FiberBenches form the foundation of a nearly infinite array of miniature fiber optic systems that customers have been building for the last decade. When used with the FiberPort Collimators/Couplers, a complete optical circuit can be constructed. The Fiber Launch Platforms are ideal for coupling a free space laser into a single mode, multimode, or polarization-maintaining fiber. Other accessories include fiber mounts, fixed and kinematic collimator adapters, and L-bracket mating sleeves.

Two-wavelength SM WDMs
-
Wavelength Division Multiplexers (WDMs) are used to combine or split two different single mode signals with low insertion loss. Thorlabs' WDMs featured on this page are manufactured using Fused Biconic Taper (FBT) technology and are designed for common NIR and telecom wavelengths (see the table to the right for options). They are an ideal solution for combining pump and signal wavelengths in fiber lasers and amplifiers or for combining telecom signals. Our WDMs have undergone extensive testing to ensure they meet or surpass Telcordia requirements; please see the Reliability Testing tab for details.
