Astrella Integrated Ti:S Amplifier

The next generation one-box Ti:Sapphire amplifier combines market-leading performance with industrial reliability.

Astrella is designed and manufactured to be at the forefront of an industrial revolution in ultrafast science. Coherent’s expertise as the proven leader in developing and consistently improving high power amplifier systems is leveraged together with advanced, stress-testing techniques developed for the production of our commercial lasers used in demanding industrial applications. This is backed up by affordable warranty packages providing up to five years of coverage. All this enables higher customer productivity and contributes to an overall lower cost of data.

Ultrafast Ti:Sapphire Amplifier

Astrella is specified to provide >7 mJ pulse energy at 1 kHz, 800 nm at either <35 fs or <100 fs pulse widths. HASS* testing is employed to ensure long term reliability and reproducibility.

The integrated, one-box design employs the new STAR regenerative amplifier module for increased energy, beam quality and stability. This is seeded by Coherent’s hands-free Vitara oscillator, and is powered by a new pump laser offering enhanced power overhead, stability and beam quality. The final, key sub-system is the advanced, sealed stretcher / compressor designed for superb dispersion compensation and durability.
