The Spectra-Physics Spitfire® Ace is the most technically advanced Ti:Sapphire regenerative amplifier available. Equipped with the proprietary XPert technology, the Spitfire Ace has set the new standard for long term performance, low noise, and day-to-day reproducibility.The XPert stabilization package incorporates multiple elements to ensure optimal performance: Newport optomechanics and Spectra-Physics proprietary optical coatings come together to deliver expert level performance. The Spitfire Ace regenerative amplifier delivers an industry leading >5.0 W of average power. To support todays demanding experiments, the system performance is guaranteed over extended periods of time, placing the Spitfire Ace in a class by itself.The Spitfire Ace Power Amplifier builds upon this highly successful platform by offering even higher energy and output power. The Power Amplifier system produces more than twice the average power of the Regen-only Spitfire Ace: at 1 and 10 kHz, the system offers >10 W; at 5 kHz, >12 W is achieved. Thanks to the patented XP cavity, the beam quality is excellent providing M2 <1.45 even at the highest energy configuration.The Spitfire Ace performs optimally when seeded using the revolutionary Mai Tai® SP oscillator. This laser is a truly hands-free system, eliminating the need for re-alignment, cleaning or adjustments of any kind. The Mai Tai SP performance specifications are guaranteed over an impressive 20°C temperature range.The Spitfire Ace amplifier system is pumped using the field-proven Empower® Q-switched DPSS laser. The regenerative amplifier can be pumped using the Empower 30 or Empower 45 versions to produce >4.0 W and >5.0 W, respectively. For highest power, the Spitfire Ace Power Amplifier system is pumped using an additional Empower laser. The combination can deliver more than 90 W of average power. Equipped with proprietary noise reducing technology, the Empower 45 is the quietest amplifier pump laser on the market.
