AdValue Photonics, a global innovator in fiber laser and supercontinuum technologies, has published a collection of technical whitepapers now featured on GoPhotonics, the leading platform for photonics news and resources. These whitepapers span a diverse range of topics, including high-power pulsed and single-frequency fiber lasers near 2 µm, all-fiber wavelength-swept laser systems, advanced mid-infrared supercontinuum generation, and novel laser-based applications such as precision plastics processing. By sharing these resources, AdValue Photonics reinforces its commitment to driving innovation in both research and industry, enabling new possibilities in spectroscopy, sensing, materials science, and manufacturing.

The following whitepapers are part of this release:

Killowatt-Peak-Power, Single-Frequency, Pulsed Fiber Laser Near 2 µm

This whitepaper examines the development and performance of high-peak-power, single-frequency (narrow linewidth) pulsed fiber lasers operating near the 2 µm wavelength regime, specifically work by AdValue Photonics and collaborators. Such lasers provide kilowatt-level peak power in nanosecond pulse durations, while maintaining a single longitudinal mode (single frequency). These sources address key needs in applications including atmospheric lidar, remote sensing, mid-infrared generation, nonlinear frequency conversion, coherent detection, and eye-safe laser technologies.

All-fiber wavelength-swept laser near 2 µm

This whitepaper highlights the development of an all-fiber wavelength-swept laser system operating near the 2 µm spectral region, leveraging Thulium-doped fiber and a high-finesse fiber Fabry–Pérot tunable filter. The system achieves a wide tuning range of 1840 - 2040 nm with a narrow output linewidth of 300 MHz, enabling high-resolution measurements across a broad span of molecular absorption lines. Its all-fiber design eliminates free-space optics, improving robustness, alignment stability, and portability for field and laboratory environments. Applications include atmospheric and environmental sensing, nonlinear mid-IR generation, remote detection, and biomedical spectroscopy. The compact architecture and precise tuning capability make this laser a versatile tool for researchers and engineers requiring reliable swept-source performance in the eye-safe 2 µm band.

Single-frequency gain-switched Ho-doped fiber laser

This whitepaper describes recent advances in all-fiber wavelength-swept lasers operating in the 2 µm spectral region. The work demonstrates a fully fiber-integrated swept-source laser using Thulium-doped fiber, driven by a fiber Fabry-Pérot tunable filter, achieving high finesse, narrow instantaneous linewidth, and broad wavelength tuning (200 nm). These systems are emerging as powerful tools for high-sensitivity spectroscopy, environmental sensing, biomedical imaging, and nonlinear optical conversion. Because the architecture is all-fiber, they offer robustness to alignment, enhanced environmental stability, and compact form factors.

2 µm Lasers enable versatile processing of plastics

This whitepaper describes the development and use of fiber lasers operating at 2 µm wavelengths, demonstrating their ability to process plastics with high precision, efficiency, and minimal thermal damage. Such lasers offer advantageous absorption characteristics in many polymers, allowing cutting, welding, marking, and surface modification with improved edge quality and reduced melt zones. The technology supports industrial, manufacturing, and research workflows where conventional lasers (e.g. CO2, fiber lasers at shorter wavelengths) may cause undesirable heating or lack sufficient absorption. All-fiber architectures contribute to stability, compactness, and ease of integration.

High-spectral-flatness mid-infrared supercontinuum generated from a Tm-doped fiber amplifier

This whitepaper highlights the development of supercontinuum light sources capable of generating broad, flat spectral output in the mid-infrared (mid-IR) region. By employing nonlinear fibers or waveguides pumped with high-quality lasers, these sources provide continuous broadband radiation that covers the molecular “fingerprint” region (2.5 to 10 µm and beyond), offering high brightness and uniform spectral power distribution. Such characteristics make them ideal for chemical sensing, environmental monitoring, materials science, and cultural heritage studies, where simultaneous detection of multiple absorption features significantly enhances sensitivity and reduces measurement times compared to narrowband or discrete sources. Moreover, their ability to enable non-destructive and remote analysis makes them particularly valuable for investigating delicate, rare, or hard-to-access samples in both laboratory and field environments.
