2016
A protocol to detect and automate mode locking in a pre-adjusted nonlinear polarization rotation fiber laser is presented. The detection of a sudden change in the output polarization state when mode locking occurs is used to command the alignment of an intra-cavity polarization controller in order to find mode-locking conditions.

A methodology is described herein for representing anatomical imaging data within crystals. We create scaled three-dimensional models of biomedical imaging data for use in Sub-Surface Laser Engraving (SSLE) of crystal glass. This tool offers a useful complement to computational display or three-dimensionally printed models used within clinical or educational settings.

In Vivo Single-Fiber Recording of Sciatic Nerve C-Fibers in Rats
0 Views •
2025
This video demonstrates a single-fiber recording of C-fiber nerve conduction in rats. An anesthetized rat is incised to expose the sciatic nerve, which provides sensory and motor supply to the lower limbs. The individual C-fibers are then exposed. Electrical stimulation is provided using stimulus electrodes implanted in the foot, and a response is recorded from a single nerve fiber.
FAQs
The rare-earth dopant in the optical fiber enables stimulated emission, allowing the fiber to generate and amplify the laser light used for marking. This amplification architecture supplies a controlled beam for selective surface processing rather than relying on a contact tool. In engineering systems, that supports consistent pattern placement and repeatable marking across manufactured components.
Material response depends on the interaction between the focused beam and the selected processing settings. The surface may undergo ablation, meaning material removal, melting, or controlled discoloration. These different effects let engineers tailor the visible or physical mark to the workpiece, which is important when the desired result is a pattern, text, or code.
Fiber Laser Engraving achieves precision by concentrating heating at a selected location while keeping the process noncontact. Accuracy helps place detailed marks, and repeatability helps reproduce the same result across parts. Together, these characteristics make the technique suitable for production environments where identification or serialization must remain consistent from component to component.
Its accuracy and repeatability make the technique compatible with automated production, where the same marking task can be applied across manufactured parts. Automation is especially relevant for identification and serialization because consistent marking supports organized component handling and traceability. The method can therefore connect marking with production and quality-control workflows.
A basic workflow begins by selecting the workpiece and intended mark, then choosing processing settings suited to the desired surface effect. The beam is focused on the target area, and the system applies it selectively to produce the pattern, text, or code. The finished mark can then support identification, traceability, or serialization.
Engineering applications include part identification, traceability, serialization, and component decoration. The method can mark metals, plastics, and other manufactured materials, allowing organizations to place durable patterns, text, or codes on components. Its precision and repeatability also make it relevant to quality-control activities and automated fabrication environments.
