Spitfire® Ace™
The Spitfire® Ace™ is Spectra-Physics' flagship amplifier system and the most technically advanced Ti:Sapphire regenerative amplifier commercially available.

Manufacturer: Spectra-Physics — USA
Overview
The Spitfire® Ace™ is Spectra-Physics' flagship amplifier system and the most technically advanced Ti:Sapphire regenerative amplifier commercially available. Equipped with the proprietary Ace cavity design, it provides guaranteed long-term performance, low noise, and reliable day-to-day operation for consistent OPA performance and nonlinear wavelength conversion. The Spitfire Ace regenerative amplifier produces an industry-leading average power of more than 7 W at 1 kHz and 10 kHz, and 8 W at 5 kHz, with excellent beam quality, making it ideal for pumping multiple OPA systems and driving a wide range of nonlinear spectroscopies.
Exceptional Quality and Performance
The Spitfire Ace amplifier builds upon the highly successful Spitfire platform, with every component carefully evaluated and selected to maximize stability. It produces an industry-leading average power of more than 7 W at 1 kHz and 10 kHz, and 8 W at 5 kHz, with excellent beam quality.
Excellent Stability
The Spitfire Ace provides the most stable output available from a Ti:Sapphire regenerative amplifier, making it ideal for pumping multiple OPA systems and driving a wide range of nonlinear spectroscopies.
