LIMO Lissotschenko Mikrooptik GmbH has recently delivered the key technology for the trend towards increasingly powerful laser outputs, with its new Fused Silica optics for high-performance laser diodes up to 500 W per bar.
The new high-performance laser systems with outputs upwards of 10 kW are currently in high demand for hardening, additive manufacturing, cutting and welding applications, for example. “But all of these applications require high-performance optics which convert the raw beam from the laser source into the most symmetrically shaped beam possible,” says Dr. Oliver Homburg, Director of Product Management for Optical Solutions at the Dortmund-based LIMO Lissotschenko Mikrooptik GmbH.
As laser output increases, the task of concentrating the laser light into a high-energy precision beam with high efficiency and extremely low losses becomes more and more challenging. The new High Power BTS (Beam Transformation System) from LIMO is produced from ultra-pure Fused Silica with a minimum content of oxygen-hydrogen bonds.
The new BTS can be used to both couple laser light into a circular fiber and produce a free laser beam. The system comprises the Fast Axis Collimator FAC160 (which is optimized for short focal lengths) and a diagonal lens array for a 90° rotation of the laser beam. It comes preassembled on a glass block (bottom tab) for easier handling.
