Pulsed Fiber Laser

L15187

This is an embedded only nanosecond pulsed fiber laser of linear polarization type with high reliability. Individual control of pulse width and pulse repetition rate is available, so machining condition for various applications can be set by the customer. In addition, output waveform can be set as desired when shipped from the factory.

Features

  • Average output power: 30 W
  • Independent control of pulse width and pulse repetition rate
  • Linear polarization
  • High beam quality
  • Fiber out type

Applications

  • Marking (surface modification)
  • Thin film removal
  • Trimming
  • Cutting
  • Drilling
  • Soldering
  • Plastic welding
  • Laser chemical vapor deposition

*1 The maximum average output power may be lower than 30 W depending on pulse width and pulse repetition rate used.
*2 If you wish to have pulse width and pulse repetition rate operate at a value other than specification, please contact our sales representative.
*3 At 80 kHz. Average output power / Pulse repetition rate
*4 Time taken to reach 10 % ⇔ 90 % of the steady state value. Adjusted at the time of shipment so that overshoot does not occur at the maximum output. Adjusting the start delay allows optimization for each condition used. (output power, pulse width, repetition rate)
* Evaluated condition: When not specified, set at an ambient temperature of 22.5 °C ± 2.5 °C, repetition rate of 200 kHz, pulse width of 700 ns, and average output power of 30 W.
