Solstice Ace


  • Unsurpassed operating stability
    and stable operation over
    a 10°C temperature range
  • Patented Ace regenerative amplifier cavity design
  • Configurable pulse widths
    from <35 fs to <120 fs
  • Configurable repetition rate,
    1–10 kHz

The Spectra-Physics® Solstice® Ace was the first femtosecond ultrafast amplifier designed, built and tested to meet rigorous industrial standards. Solstice Ace incorporates modular components, adjustment-free mounting hardware, and field proven pump and seed lasers. The result is an industry-leading, hands-free ultrafast light source for a wide range of ultrafast applications.

Unsurpassed Operating Stability

Solstice Ace is capable of reliable operation over a ±5°C temperature range. Unlike traditional lasers that utilize standard optomechanics, Solstice Ace employs adjustment-free EternAlign™ optical mounts to maximize long-term stability and performance. The regenerative amplifier and the stretcher/compressor are housed in 2 independently temperature stabilized enclosures to ensure optimal reliability. With the Solstice Ace revolutionary design, both short term and long term stability are maximized.

Using Spectra-Physics’ patented Ace regenerative amplifier cavity, the Solstice Ace delivers >7 W at 1 kHz, >8 W at 5 kHz and >7 W at 10 kHz with pulse width configurations ranging from <35 fs to <120 fs. For every configuration of Solstice Ace, the beam quaity is exceptional (M2 <1.25) making it perfect for OPA pumping and a wide range of nonlinear spectroscopy applications.
