Femtosecond Terawatt Ti:sapphire Laser System

MPA-XL is a cost-effective terawatt Ti: sapphire amplifier system. It gives up to 200 mJ energy of the stretched pulse and further compression with 65% efficiency. A standard air compressor can be placed into a custom designed vacuum chamber.

The system configuration:

  • TISSA 20 femtosecond Ti: sapphire seed oscillator with built-in pump laser
  • Femtosecond pulse stretcher
  • Two-mirror confocal multipass first stage amplifier with a pump laser
  • 4-pass second stage amplifier with a pump laser
  • Femtosecond pulse compressor
  • Single shot autocorrelator
Total system dimensions: 3.5 m x 0.8 m


  • Pulse repetition rate: 10 Hz
  • Maximum pulse energy of amplified stretched pulses: 0.2 J
  • Output pulse wavelength: 810 ± 10 nm
  • Output spectral bandwidth: 30 nm
  • Output beam diameter: 15 mm
  • Output beam quality: M2<2
  • Contrast: >106 for ns time scale
  • Compressor efficiency: 65%
  • Pulse width after compressor: <40 fs
  • Recommended maximum pulse energy after air compressor: 60 mJ (1.5 TW at 40 fs)
  • Output beam polarization: Horizontal
