LIGHT PANTHER
High energy laser delivery through optical fiber
The LightPanther is a fiber-based laser transmission system designed to deliver high-energy nanosecond pulses at the tip of a standard silica fiber. It enables the deployment of high-energy laser processes by decoupling the laser source from the processing location, while preserving pulse energy and duration.
Industrial challenge
High-energy laser processes remain difficult to deploy in industrial environments when they rely on conventional free-space beam delivery. These setups typically require Class IV lasers, dedicated installations, and the positioning or disassembly of parts before treatment. This limits flexibility for maintenance, in-situ operations, and use in constrained environments.
Fiber-based breakthrough
Our system enables the transmission of high-energy nanosecond laser pulses through optical fibers using a dedicated beam-shaping architecture. This approach reduces the spatial coherence of the laser beam and limits intensity peaks at the fiber input, enabling high-energy coupling into fibers. Peak powers exceeding 60 MW have been demonstrated in the nanosecond regime.
Core capabilities
The LightPanther provides features designed for high-energy pulsed laser delivery:
- High-energy transmission up to hundreds of mJ per pulse
- Pulse duration around 6 ns
- Fiber length up to 60 m
- Standard single-core silica fibers
- Output beam shaping options such as circular, square or linear profiles
- Stable top-hat intensity profile at the fiber output
The system can be used in both fixed and mobile configurations, including handheld or robot-arm operation.
Monitoring and control
Our solution includes a dedicated software environment for controlled and reliable operation. Main functionalities include:
- Real-time monitoring of the fiber input facet
- Automatic interruption of lasing in case of detected fiber damage
- Energy control and operation modes such as single-shot, continuous and burst
- Assisted fiber alignment and replacement by the user
