Coherent Astrella Ultrafast Ti:Sapphire Amplifier

Next generation one-box Ti:Sapphire amplifier combines market-leading performance with industrial reliability


Astrella and Astrella HE are 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.



  • Integrated Vitara seed laser, new pump laser, STAR regenerative amplifier and sealed, compact stretcher/compressor for ultimate stability and reliability
  • HASS-tested for superior product quality and reliability
  • STAR regenerative amplifier engine, high performance and reliability module
  • All major sub-systems thermally-stabilised for reliable long-term performance
  • Innovative, water-only cooled Ti:Sapphire rod assembly for improved beam quality and thermal management
  • Sealed stretcher/compressor section with advanced dispersion management for clean, short pulses
  • Energy >5 mJ, or >7mJ, or >9mJ at 1kHz, >7W or >10W at 5kHz
  • Pulse Width <35fs or <100fs
  • Stability <0.5% rms
  • Beam quality M2 <1.25

Astrella and Astrella HE have options specified to provide up to >9 mJ pulse energy at 1 kHz or >10W at 5 kHz, and either <35 fs or <100 fs pulse widths. HASS (Highly Accelerated Stress Screening) 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 Coherents 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.
