Beam Transformation Systems (BTS)
- ● The BTS transforms the asymmetrical far field distribution of a diode laser bar into a nearly symmetrical beam parameter product.
- ● Equipped with anti-reflective coatingto lower the absorption for high-power applications
- ● Applications: Collimation of free beam lasers; efficient fiber coupling for high-power diode laser bars; BTS made of fused silica optimized for highest power densities
