High Power Pulsed Single Mode 1550nm Laser Source

(SM or PM output fiber, up to 10W output power)

DATASHEET

Agiltron's high-power pulsed 1550nm fiber lasers deliver eye-safe, single-mode nanosecond pulses with up to 10W average output power and near diffraction-limited beam quality. Built with high-reliability, all-fiber construction using double-cladding fiber pumping technology, they efficiently convert multimode input into coherent single-mode output. Available as modules or turn-key units with feedback power stabilization and integrated power supplies, these lasers offer optional special high-reflection-power isolators for protection against strong back reflections. Custom designs, output beam collimators, and wavelength stabilization options are also available to meet specific application needs, ensuring optimal performance in demanding environments.

Application Notes

Fiber Core Alignment

Note that the minimum attenuation for these devices depends on excellent core-to-core alignment when the connectors are mated. This is crucial for shorter wavelengths with smaller fiber core diameters that can increase the loss of many decibels above the specification if they are not perfectly aligned. Different vendors' connectors may not mate well with each other, especially for angled APC.

Fiber Cleanliness

Fibers with smaller core diameters (<5 μm) must be kept extremely clean. Contamination at fiber-fiber interfaces, combined with the high optical power density, can lead to significant optical damage. This type of damage usually requires re-polishing or replacement of the connector.

Maximum Optical Input Power

Due to their small fiber core diameters for short wavelength and high photon energies, the damage thresholds for the device is substantially reduced compared to the common 1550nm fiber. To avoid damage to the exposed fiber end faces and internal components, the optical input power should never exceed 20 mW for wavelengths shorter than 650 nm. Agiltron produces a special version to increase the handling by expanding the core side at the fiber ends.
