Astrella / Astrella HE Integrated Ti:S Amplifier

Ultrafast Ti:Sapphire Amplifier

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 (STable ARchitecture) 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 overhead, stability, and beam quality. The final, key sub-system is the advanced, sealed stretcher/compressor designed for superb dispersion compensation and durability.
