Technology - Fiber-delivered Ultrashort Pulses on Demand

Fiber-delivered Ultrashort Pulses on Demand


There is an increasing demand for laser systems that can generate ultrashort, high-energy pulses with tunable repetition rates. However, traditional ultrafast laser systems, especially those built from free space optical components, are highly sensitive to misalignment, high maintenance, and lose pulse quality when the repetition rate is altered. Industrial and research applications such as spectroscopy, optical coherence tomography, telecommunications, two-photon microscopy, neurosurgery, and micromachining increasingly require laser sources that are compact, stable, and capable of delivering fiber-based femtosecond pulses on demand. Conventional systems struggle with pulse stretching, nonlinear distortion, or loss of energy when operating at variable repetition rates, particularly due to group delay dispersion and self phase modulation in fiber, which limit scalability, stability, and commercial deployment.

Technology Overview:


This technology introduce s a fully fiber-integrated system that generates femtosecond laser pulses at arbitrary repetition rates from 0 to 60 MHz while preserving pulse energy and shape. Instead of relying on mechanical components to choose pulses, the system uses fiber-integrated modulation techniques to direct selected pulses for amplification while preserving pulse quality. After amplification and spectral shaping within fiber, the pulses are recompressed to ultrashort durations and delivered through a robust, alignment-free architecture. By eliminating bulky optics and mechanically sensitive components, the platform enables a compact, robust, and easily deployable laser source suitable for demanding applications. Its design improves operational stability, reduces system downtime, and enhances long-term reliability, making it well-suited for biomedical imaging, precision manufacturing, and communication systems requiring on-demand, high-quality ultrafast pulses.
