    Femtosecond disk laser


    At SPIE Photonics West 2016 in San Francisco, 13-18 February, Jenoptik will introduce a 16-W version of its established JenLas® femto series for industrial micro-machining.

    The JenLas® femto 16 features a pulse energy up to 80 microjoules, a free and quickly adjustable pulse repetition rate from 100 to 510 kilohertz, single shot ability, an internal SHG option (THG on request) and reliable operation at up to 35°C ambient temperature.

    The performance of this femtosecond laser is ideal for drilling injection nozzles and also provides a high productivity in cutting and structuring processes, at higher material removal rates compared to picosecond pulses.

    The Yb-doped laser's typical pulse width of 550 femtoseconds facilitates processes such as:

    • non-thermal ablation of nearly all materials (damage- and burr-free processing of Polymers, NiTi, etc.)
    • nonlinear absorption in transparent materials (efficient machining of Sapphire or Glass)
    • material-selective ablation in multi-layer systems
    • inner marking of transparent materials
    • scribing of invisible pre-determined break lines
