Laser Diodes
Laser diodes ranging from 600 nm to 2500 nm for industrial and custom applications
IMM Photonics offers laser diodes for sensor technology, industrial measurement, medical technology, life sciences, data communication, and research. The standard portfolio covers wavelengths from 600 to 2500 nm and optical output powers from 5 mW to 100 W. Available products include Fabry-Perot laser diodes and VCSELs from Union Optronics, Eblana Photonics, SemiNex, and QD Laser—as compact TO-CAN devices, in other package types, or as fiber-coupled and custom-integrated solutions.
Selecting the Right Laser Diode for Your Application
Wavelength and optical power are not the only factors that determine the right choice. Operating mode, spectral width and stability, beam profile and divergence, temperature range, housing, pin configuration, and optical, electrical, and thermal integration must all be taken into account. IMM Photonics provides support with technical preselection and integration—from collimation and focusing to line generation and beam shaping, all the way to fiber coupling.
Manufacturer-independent — from laser diodes to production-ready laser modules
If no standard laser diode meets your specifications, IMM Photonics will also evaluate components from other manufacturers and additional wavelength ranges, such as green from 500 to 575 nm, blue from 400 to 500 nm, and UV below 400 nm. Technical suitability and availability are confirmed on a project-by-project basis.
If needed, we develop and manufacture custom laser modules and optoelectronic assemblies. We integrate optics, electronics, mechanics, and thermal management into a ready-to-install solution—from the initial product concept and feasibility study through prototyping to mass production.
Your Technical Inquiry
For a quick preliminary selection, please provide us with the wavelength, optical power, operating mode, temperature range, desired package type, optical interface, available mounting configuration, quantity, and scope of integration. This will allow us to evaluate a suitable laser diode or a custom laser source in a targeted manner.

Frequently Asked Questions
What wavelength should a laser diode have?
The appropriate emission wavelength depends on the application: key factors include, in particular, the absorption, transmission, or fluorescence of the target material, the spectral sensitivity of the detector, and the losses and coatings of the optics and fibers used. In addition, the optical output power, spectral width, wavelength stability, beam profile, operating mode, and permissible temperature range must be compatible with the overall system.
What is the difference between a Fabry-Perot laser diode and a VCSEL?
A Fabry-Perot laser diode is typically an edge-emitting semiconductor laser: the light emerges parallel to the chip surface; the beam is usually elliptical and exhibits different divergences along the fast axis and slow axis; furthermore, multiple longitudinal modes may occur. A VCSEL (Vertical-Cavity Surface-Emitting Laser) emits perpendicular to the chip surface and often offers a nearly circular beam profile, low threshold currents, and is well-suited for compact designs and arrays. The selection depends, among other factors, on wavelength, power, mode behavior, beam quality, modulation requirements, and integration concept.
Welche Bauformen gibt es bei Laserdioden?
Laserdioden sind beispielsweise als Chip beziehungsweise Bare Die, in TO-CAN-Gehäusen, auf B-Mount- oder C-Mount-Trägern sowie in Butterfly-Gehäusen erhältlich. Hinzu kommen fasergekoppelte Baugruppen und Multi-Chip-Module. Dabei sind nicht alle Begriffe gleichbedeutend: TO-CAN, Butterfly, B-Mount und C-Mount bezeichnen Gehäuse- oder Montageformen, während fasergekoppelte Lösungen und Multi-Chip-Module bereits einen höheren Integrationsgrad besitzen. Für die Auswahl sind unter anderem Verlustleistung und Kühlung, Pinbelegung, ESD-Schutz, Bauraum, optische Schnittstelle, Strahlführung und Montageprozess entscheidend.
Wann ist eine Monitor-Photodiode sinnvoll?
Eine integrierte Monitor-Photodiode erfasst einen zur emittierten Laserleistung korrelierten Anteil des Lichts. Zusammen mit einem geeigneten Laserdiodentreiber kann sie für eine automatische Leistungsregelung im APC-Betrieb (Automatic Power Control) eingesetzt werden und dadurch Änderungen infolge von Temperatur oder Alterung teilweise kompensieren. Erforderlich sind eine passende Beschaltung sowie die Berücksichtigung von Polarität, Monitorstrom und Kalibrierung im jeweiligen Datenblatt. Für eine präzise Messung der tatsächlich am Ziel oder am Faserende verfügbaren Leistung kann dennoch ein externer Detektor notwendig sein.
Are laser diodes available for high temperatures?
Yes. Among other products, IMM Photonics offers quantum-dot laser diodes in the 1300–1310 nm range that are designed for elevated operating temperatures. Depending on the model, operating temperatures of up to 150 °C or 200 °C are possible. The binding limits, the permissible optical power, and any potential reductions in power or lifetime at high temperatures can be found in the respective data sheet.
Can IMM Photonics integrate laser diodes into a module?
Yes. IMM Photonics develops and manufactures custom laser modules and optoelectronic assemblies based on suitable laser diodes. Depending on the project, the scope of integration may include collimation and beam shaping, fast-axis and slow-axis collimation, free-space or fiber coupling, mechanical mounting, thermal management, and the integration of driver and sensor electronics. The optical, electrical, thermal, and mechanical interfaces, as well as the requirements for prototypes and series production, are decisive factors.
What specifications are required to select a laser diode?
To make a reliable preliminary selection, the following information is required at a minimum: the target wavelength with its permissible tolerance, the required optical power at the emitter or at the system output, the operating mode (CW or pulsed), and—for pulsed operation—the pulse duration, repetition rate, and duty cycle. Additional factors include the operating and storage temperature ranges, requirements for spectral width or mode behavior, beam profile and divergence, polarization, power and wavelength stability, desired package type, and pin configuration. For fiber-coupled solutions, the fiber type, core diameter, numerical aperture, and connector type are also relevant. Information regarding power supply, drivers, cooling, installation space, mounting configuration, environmental conditions, expected quantity, and desired level of integration is also helpful.
Are laser diodes available outside the product table?
Yes. The product table shows the standard portfolio, not all laser diodes that can be procured or integrated on a project-specific basis. Depending on technical availability, IMM Photonics can also evaluate components from other manufacturers and additional wavelength ranges and integrate them into customer-specific modules or optoelectronic assemblies. For a feasibility study, the desired wavelength, optical power, operating mode, package type, environmental conditions, quantity, and scope of integration are required. Availability and suitability are confirmed on a project-by-project basis.
