Special Issue Information
Dear Colleagues,
We are pleased to invite you to contribute to this Special Issue titled “Femtosecond Lasers: Principles, Techniques and Applications”. Over recent decades, femtosecond laser technology has experienced rapid development, driven by advances in ultrafast optics, nonlinear light–matter interactions, and precision laser engineering. The generation of optical pulses with durations on the order of femtoseconds has enabled direct access to ultrafast physical, chemical, and biological processes occurring on previously inaccessible timescales. Femtosecond lasers are now indispensable tools across a wide range of scientific and technological domains. Their unique characteristics—such as ultrashort pulse duration, high peak intensity, and minimal thermal diffusion—have led to transformative applications in precision micro- and nanofabrication, biomedical imaging and surgery, spectroscopy, optical communications, and strong-field physics. At the same time, continued progress in laser sources, pulse shaping, stabilization techniques, and system integration continues to expand both the performance limits and application horizons of femtosecond laser systems. Given the interdisciplinary nature of femtosecond laser research, there is a growing need for a specialized platform that brings together advances in fundamental principles, enabling techniques, and emerging applications. This Special Issue aims to provide such a platform by collecting high-quality contributions that reflect the latest developments and future directions in this rapidly evolving field.
This Special Issue aims to present a comprehensive overview of recent progress in femtosecond laser science and technology, spanning fundamental principles, advanced experimental techniques, and diverse application areas. The scope of this Special Issue aligns well with the mission of Photonics, which focuses on cutting-edge research in light generation, manipulation, and application. By bringing together contributions from optics, photonics, materials science, engineering, and applied physics, this Special Issue seeks to foster interdisciplinary dialogue and highlight how femtosecond laser technologies continue to shape modern photonic systems and applications. Both fundamental studies and application-oriented works are encouraged, provided that they offer clear scientific insight or technological advancement relevant to the photonics community.
In this Special Issue, original research articles and review papers are welcome. Topics of interest include, but are not limited to, the following:
- Fundamental principles of femtosecond laser generation and amplification;
- Ultrafast pulse characterization, stabilization, and control techniques;
- Nonlinear optics and strong-field interactions driven by femtosecond pulses;
- Femtosecond laser–matter interaction mechanisms;
- Micro- and nanofabrication using femtosecond lasers;
- Biomedical and clinical applications of femtosecond laser systems;
- Ultrafast spectroscopy and time-resolved measurement techniques;
- Novel femtosecond laser sources and system integration;
- Applications in optical sensing, imaging, and communication;
- Emerging applications and interdisciplinary advances enabled by femtosecond lasers.
We look forward to receiving your contributions.
