Lumics (Berlin, Germany) has introduced the LU1060F400 pulsed fiber laser that offers up to 0.8 mJ pulse energy with average power of 4W. It is a short-pulse Ytterbium fiber laser in Master Oscillator Power Amplifier (MOPA) configuration. The laser operation mode can be changed by selecting customer-specific parameters, such as output power, pulse energy, repetition rate, and pulse width, via a conventional USB interface. The laser emits at a wavelength from 1060 to 1080 nm from a fiber with a 25-um core. The fiber is a standard length of 1.5 m, terminated with an FC/APC connector. An optional collimator and focuser, as well as metal armored cable, are available.
The laser’s pulse energy is rated with 0.8 mJ at 5-kHz repetition rate, and 100-ns pulse width. The repetition rate adjusts from 5 to 100 kHz. The pulse width adjusts from 30 to 400 ns. The TTL control interface is specified with a DB9 connector. The laser has an industry-type housing with an external power supply and driver software. Dimensions are 284 × 180 × 50 mm, allowing integration into existing equipment.
