LuOcean 1,940nm diode laser

Lumics has introduced the 1,940nm LuOcean laser diode source for medical customers, which delivers an output power of 10W at 1,940nm, delivered out of a standard silica fibre with a 20μm fibre core (numerical aperture 0.22). The water absorption peak at 1,940nm has a five times higher absorption rate compared to the peak at 1,470nm, which allows five times lower penetration depth in tissue and is therefore suited to surgery. The laser diode module is easy to integrate with a single electrical interface with an industry standard D-sub connector and an SMA-905 fibre connector. For medical applications, the unit can be configured with a red or green pilot beam, thermistor, fibre interlock, monitor diode and user-exchangeable protection window. Operating current and voltage at 10W is 4.5A and 20V, and spectral width of light is 10nm. Unit size is 180 x 80mm. The module operates from 15 to 40°C even with air-force cooling. Upon request, Lumics can offer all LuOcean laser modules with a laser diode driver as a compact, turnkey solution. The LuOcean series comprises diode lasers with different footprints from 793–1,940nm with output powers up to 900W.
