Berlin, Germany - Lumics GmbH-Berlin has announced its 1940 nm laser diode source for medical customers. This product is based on the field-proven LuOcean Series and delivers an output power of 10 W at 1940 nm. It delivers that power level out of a standard silica fiber with only a 200 micron fiber core, NA 0.22.
The important water absorption peak at 1940 nm has a five times higher absorption rate compared to the peak at 1470 nm, which allows five times lower penetration depth in tissue and is therefore ideally suited for 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 fiber connector. For medical applications, the unit can be configured with a red or even green pilot beam, thermistor, fiber interlock, monitor diode and user-exchangeable protection window.
Operating current and voltage at 10 W is 4.5 A, and 20 V and spectral width of light is 10 nm. Unit size is 180 mm x 80 mm. The module operates from 15 to 40°C even with air force cooling.
