Excimer Laser Suited to Fiber Bragg Grating (FBG) Writing

Published on February 19, 2012 at 6:19 PM

The new BraggStar M from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) delivers high pulse energy and superior 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 since it enables creation of FBGs with higher contrast and/or longer length. And because it can be operated at repetition rates of up to 100 Hz, the BraggStar M supports high throughput production of FBGs.

The new BraggStar M from Coherent, Inc.

The BraggStar M uses a coherence-enhanced optical design at the dominant FBG-writing wavelength of 248 nm, resulting in significantly higher spatial coherence compared to conventional, broad-use excimer lasers. This new laser also features the twin advantages of a compact design and ease of operation. Moreover, the new BraggStar M is based on the field-proven COMPex platform that is specifically designed for high reliability. The success of the high-reliability COMPex platform is evidenced by the more than 2,500 installed units worldwide.

The BraggStar M is ideal for creating FBGs for a broad range of applications. These include reflectors in fiber lasers and reference wavelength stabilization in wavelength division multiplex (WDM) telecom apps, as well as fiber sensing applications.

Founded in 1966, Coherent, Inc. is a Russell 2000 Index company and a world leader in providing laser-based solutions to the commercial and scientific research markets.
