Fiber Bragg Gratings (FBGs) are basic elements in DWDM technology. To meet the demands of the FBG writing industry, Tuilaser has designed a new UV light source with a temporal coherence length of 5 mm, the BraggStar Industrial-LN. Hence it is possible to utilize cost efficient excimer laser technology for the interferometric FBG writing process.

The BraggStar Industrial-LN can replace expensive UV light sources such as frequency doubled argon ion lasers driving interferometric FBG writing set-ups in production and R&D.

The BraggStar Industrial-LN offers the following benefits:

--High-End Technology: Corona Preionization, Solid-State-Switch, Metal/Ceramic

FutureTube Technology

--Long Temporal and Spatial Coherence Length

--Billion Pulses Hands Free Operation

--Excellent Spatial and Temporal Beam Stability

--Writes Sharp Gratings with Easy Reproducibility

--Increases Chirp and Spectrum Control and Throughput

The BraggStar Industrial-LN is a very competitive UV light source offering more flexibility and cost efficiency in FBG writing. The extended temporal coherence length and superior beam quality allow using the same set-up for different FBG writing processes saving preproduction and investment costs at the same time. In comparison to other light sources for the interferometric FBG process TUILASER's BraggStar Industrial-LN means only half investment cost. Besides negligible power requirements (40 kW for argon ion lasers vs. 1kW for BraggStar Industrial-LN) only air cooling is required.
