The MARS series 1.0 µm high power pulse fiber amplifiers from Connet Laser are engineered specifically for demanding short‑pulse applications, with pulse widths down to 10 ns and repetition rates up to 1 MHz. Based on advanced ytterbium‑doped double‑clad fiber amplifier technology, these units deliver high peak powers up to 10 kW while maintaining excellent beam quality and pulse integrity. This makes them an ideal choice for applications where a compact, efficient, and reliable pulsed amplification stage is required at typical wavelengths of 1053 nm, 1064 nm, or 1083 nm.

Unlike many generic pulsed fiber amplifiers that compromise between efficiency and nonlinear performance, the MARS series is optimized to minimize nonlinear effects such as self‑phase modulation and stimulated Brillouin scattering. The amplification chain is carefully designed to prevent spectral broadening and temporal distortion of the input pulses, ensuring that the output closely preserves the original pulse shape and spectrum. This is particularly important in coherent detection, high‑resolution fiber sensing, and precision material processing, where spectral purity and temporal fidelity translate directly into measurement accuracy and process quality.

The product line covers both single‑mode (MFAS‑Yb‑10xx‑PL) and polarization‑maintaining (MFAP‑Yb‑10xx‑PL) configurations, providing flexibility for systems that require either high spatial mode quality or strict polarization control. The PM versions are especially well suited for coherent beam combining, interferometric sensing, and polarization‑sensitive LIDAR and LADAR systems. Typical output power is around 10 W average with peak powers up to 10 kW, beam quality M² less than 1.2, and polarization extinction ratios of about 20 dB for PM models, placing these amplifiers in the performance class commonly used in advanced industrial and scientific platforms worldwide.

Thermal management plays a critical role in the long‑term stability of high‑power fiber amplifiers. The MARS series incorporates a proprietary thermal treatment approach and efficient air‑cooling design to maintain stable operation over extended periods. Combined with an intelligent high‑speed protection circuit that continuously monitors both input and output power, the system can react rapidly to abnormal conditions, helping to safeguard the internal components, the seed laser, and downstream optics. This level of protection aligns the MARS amplifiers with best‑in‑class pulsed fiber systems used in harsh industrial and field environments.

For system integrators and OEMs, the MARS series is available in multiple mechanical formats, including benchtop, rackmount, and module‑level packages. The standard configuration provides an output fiber length of at least 1 m with FC/APC connectivity (other connector types are available), simplifying integration into existing optical setups. Output power can be tuned within a defined range, enabling users to optimize average and peak power for specific tasks such as range‑resolved LIDAR, distributed fiber sensing, laser micro‑machining, or non‑linear optics experiments. The amplifiers operate from a standard AC mains input and are designed for reliable performance over a broad environmental temperature range.

Thanks to their combination of high peak power, short‑pulse capability, robust isolation, and stable optical performance, MARS series 1.0 µm high power pulse fiber amplifiers serve as a versatile backbone for a wide variety of applications. Typical uses include fiber Bragg grating interrogation, distributed acoustic or temperature sensing, time‑of‑flight and Doppler LIDAR/LADAR, biomedical diagnostics, and precision laser processing. Research laboratories and R&D teams also benefit from the amplifiers’ tunability, repeatable performance, and compatibility with common ytterbium seed lasers operating across the 1035–1083 nm range. Overall, the MFAS‑Yb‑10xx‑PL and MFAP‑Yb‑10xx‑PL models provide a compact, efficient, and application‑ready solution for modern short‑pulse photonic systems.
