Excimer Laser for FBG Writing

Coherent Inc.Request Info

The new BraggStar M from Coherent Inc. is an excimer laser that delivers high pulse energy and spatial coherence for fiber Bragg grating (FBG) writing.

High pulse energy is a critical advantage in some FBG writing applications, and high spatial coherence is always beneficial because it creates FBGs with higher contrast and/or longer length. Because it can be operated at repetition rates of up to 100 Hz, the BraggStar M supports high-throughput production.

It uses a coherence-enhanced optical design at the dominant FBG-writing wavelength of 248 nm, resulting in higher spatial coherence compared to conventional, broad-use excimer lasers, the company said. Featuring a compact design and ease of operation, it is based on the field-proven COMPex platform that is designed for high reliability.

The laser creates FBGs for reflectors in fiber lasers, reference wavelength stabilization in wavelength division multiplexing telecommunications, and fiber sensing applications.
