FCPA DX Series


High Pulse Energy Ytterbium-Doped Femtosecond Fiber Lasers

The most compact laser form based on IMRA’s patented Fiber Chirped Pulse Amplification (FCPA) technology.  The DX Series lasers offer sufficient pulse energy for selected material processing at a near-infrared wavelength of 1045 nm with an ideal compact form factor.  Harmonic generation packages, which convert its output to visible and UV wavelengths, are available.  The FCPA architecture allows users to choose between high energy operation up to 40 µJ pulses, repetition rate up to 5 MHz, and average power up to 10 W depending on the specific source.  The DX Series allow for material processing at fast rates in a light-weight package.

Typical Configurations

  • Pulse Select: Allows users to select up to 15 pre-set repetition rate values; typical pre-select repetition rates range from 100 kHz to 5 MHz
  • Pulse Pick: Enables operation from an on-demand single pulse to high repetition rates up to 100 kHz
  • Pulse Flex: A combination of Pulse Select and Pulse Pick; offers the possibility to operate the laser from an on-demand single pulse all the way up to 5 MHz
  • Harmonic Module: Attachable to the laser head to convert its output to visible and/or UV wavelengths
  • Burst Mode: Provides bursts of pulses within pre-determined boundary conditions
