Ultrafast Ti:Sapphire Amplifier Astrella and the new Astrella HE are next-generation, ultrafast, kHz amplifiers that are the first to combine industry-leading performance and industrialized durability. Manufactured to Coherent’s rigorous standards using advanced stress-testing techniques, the one-box Astrella system enables a wide range of demanding scientific applications and operating conditions, offering higher productivity and lower data acquisition costs. Delivering high (up to >9 mJ/pulse) energy, a range of pulsewidth options from <35 fs to <100 fs, and excellent beam quality (M2 <1.25), Astrella is ideal for ultrafast spectroscopy, THz studies, femtosecond micromachining, etc. With unmatched performance, reliability and affordability, Astrella stands at the forefront of the industrial revolution in ultrafast science. • One-box, industrialized platform • HASS* verified for quality and reliability • >5 mJ, >7 mJ or >9 mJ pulse energies • <35 fs, <60 fs, <80 fs, or <100 fs pulse width options • High performance STAR regen amplifier (water-only cooling) • Hands-free Vitara oscillator • Revolution pump laser for performance overhead • Sealed stretcher/compressor section with advanced dispersion management for clean, short pulses • Thermally-stabilized sub-systems for long term stability • Time-resolved Spectroscopy • Multidimensional Spectroscopy • Surface SFG/SHG • Stimulated Raman Scattering * HASS – High
