Laser components & accessories
Configurable free-space, pigtailed and fiber-coupled laser diodes covering 375–1610 nm, from low-power single-mode and narrow-linewidth DFB devices to high-power pump modules up to 500 W. Select wavelength, output power, fiber mode, connector, thermal control and mounting as one integrated build.
| Architecture | Wavelength range | Output power | Optical interface and defining feature |
|---|---|---|---|
| Free-space Fabry–Perot | 405–1550 nm | 20 mW–10 W | Single-mode or multimode output; low capacitance |
| Pigtailed Fabry–Perot | 380–1550 nm | 1 mW–10 W | SM, PM or MM fiber; FC/PC or FC/APC optional |
| DFB laser diode | 1290–1610 nm | 10–20 mW | 3 MHz linewidth; SM or PM fiber |
| High-power fiber-coupled module | 375–1550 nm | Up to 500 W | Fiber-delivered pump or process source |
| Subsystem | Selection input | Integration consequence |
|---|---|---|
| Optical output | Free-space or fiber-coupled | Sets the launch optics, alignment method and enclosure layout |
| Fiber delivery | SM, PM or MM; FC/PC or FC/APC | Determines mode matching, polarization behavior and back-reflection |
| Current control | Diode current and modulation requirement | The driver must match maximum current, compliance voltage and modulation bandwidth |
| Temperature control | TEC requirement and wavelength stability target | Temperature regulation controls wavelength drift, efficiency and operating life |
| Thermal hardware | Heat sink or cooled module | Waste heat must be removed at the selected optical power and duty cycle |
| Mechanical mounting | Package drawing and mount kit | The package must be clamped without stress and adapted to the optical table |
Application context
Application fit depends on the ordered configuration; catalog values are separated from fields that still require confirmation.
Laser Diode Component: high-power fiber-coupled modules concentrate pump power into a controlled fiber core, allowing the delivery numerical aperture and wavelength to be matched to the gain medium while keeping the heat-producing diode package away from the resonator.
Laser Diode Component: a 3 MHz DFB option is used when spectral selectivity and wavelength repeatability matter more than broadband optical power. The selected emission band must also match the sample transition, coatings and detector response.
Laser Diode Component: fiber-coupled power delivery simplifies routing into a process head, but wavelength, core diameter, numerical aperture and continuous or modulated power determine the achievable spot size and absorbed power density.
Laser Diode Component: compact fiber delivery can place optical energy at a remote treatment or diagnostic site. Wavelength is selected for the intended tissue or chromophore interaction, while connector, fiber, thermal control and interlocks are specified as part of the complete instrument.

Technical FAQ
Choose a free-space Fabry–Perot diode for direct beam access, a pigtailed diode for compact fiber delivery, a DFB diode when narrow linewidth near 1290–1610 nm is central to the measurement, or a high-power fiber-coupled module for pumping and direct-diode processing. Final selection also depends on wavelength, power, spectral width, beam or fiber parameters and modulation requirements.
Specify the wavelength and power first, then choose single-mode, polarization-maintaining or multimode fiber and the required termination. FC/PC and FC/APC are optional interfaces on the pigtailed family; they are not interchangeable because their end-face geometry and return-reflection behavior differ.
The current controller must match the diode maximum current, compliance voltage and any analog or digital modulation. Pair the package with its specified temperature controller, heat sink or cooled module so junction temperature remains within limits; do not choose a driver or mount from optical power alone.
Yes, with the package-specific mount kit or an adapter plate. Confirm the mechanical drawing, clamping method and bolt length before installation rather than assuming the diode package itself contains M6 threads.
