The above image shows the end face of a square core fiber.
SQUARE CORE FIBERS deliver top hat beam profi le and exclude the need of beam shaping optics, which in turn reduces the size and complexity of the laser delivery system.
SQUARE CORE FIBERS have better coupling e fficiency with conventionally shaped laser diodes than circular core fi bers.
SQUARE CORE FIBERS are ideal for use in laser scribing machines. The uniform top hat laser beam from square core fibers can improve the laser scribing speed and processing form.
Advantages
The highly homogenous beam profi le of a square core fiber.
Better coupling e fficiency with square shape diode lasers.
Delivers highly homogenous top hat laser beam.
Eliminates the need for beam shaping optics
