"One-way" optical device minimizes fiber laser damage
Optical isolator is a key device blocking optical feedback from target materials. This function not only prevents fiber lasers from damage but also stabilize laser beam output power. Although garnet crystal called 'TGG' is generally used for optical isolator specifically for fiber lasers, Fujikura applies special crystal called 'TSLAG' co-developed with NIMS (National Institute for Material Science of Japan) to its fiber laser products. TSLAG contributes to high quality, low cost production of optical isolators as the crystal is better suited for large size, homogeneous configuration in production from the perspective of its constituent materials.
