Fibre-coupled 405 nm Laser Diodes
Our range of fibre-coupled high-power laser diodes is increasing more and more; for example, the K41 and CS405 series have recently been added. At 405 nm, output power from the fibre varies from 20 mW to 100 mW. Optimum optical and electronic performance is achieved through the unique alignment of the 3 µm to 60 µm fibres.
In addition to an outstanding coupling efficiency, the fibre connection features long-term stability and optimal beam performance. If desired, we may also equip the fibre end with an optical connector: here you have a choice between FC, ST, and SMA connectors.
The K41 series emits up to 100 mW from a 60 µm multimode fibre with a numerical aperture of 0.22 and up to 30 mW from a 3µm single-mode fibre with an NA of 0.12.
The CS405 series achieves an even better coupling efficiency, emitting 60mW from a 4.5 µm fibre with an NA of 0.06.
All components are supplied in a robust metal housing. Depending on the design, the powerful laser diodes are also available with a thermoelectric cooler and/or a thermistor. They are thus ideally suited for use in medical technology, material processing, illumination, printing, biochemical analyses, or scientific applications.
