The FemtoSource Fusion family manufactured by Femtolasers Produktions GmbH is a range of Ti:sapphire oscillators generating pulse durations from <9 to <20 fs. Average powers range from 150 mW to 1.2 W, and the pulse durations of <9 fs yield peak powers of >1 MW. State-of-the-art laser parameters are offered at lower pump power levels compared to the device’s counterparts, the company says. The systems feature an integrated pump laser and the GreenAlign active optomechanical component developed for the proprietary industrial-grade Integral oscillators. Applications include amplifier and optical parametric chirped-pulse amplification seeding, terahertz spectroscopy and imaging, OCT, ultrafast spectroscopy, pump-probe measurements, materials processing, two-photon polymerization, thin-film metrology, nonlinear optics and surface-enhanced high harmonic generation.
