UltraFlux is the first compact high energy tuneable wavelength femtosecond laser system which
incorporates the advantages of ultrafast fiber laser, solid-state and parametric amplification
technologies in less than 1 square meter footprint box. Patent pending
(application No. EP2924500) OPCPA front end technology uses the same
picosecond fiber laser for seeding both picosecond DPSS pump laser and femtosecond parametric amplifier by spectrally broadened output. This approach greatly simplifies the system – excludes femtosecond regenerative amplifier and eliminates the need of pump and seed pulse synchronization. In addition to that, contrast of the output pulses in picosecond to nanosecond time scale is potentially increased. System generates down to 35 fs pulses, which can be automatically tuned in 700 – 1010 nm wavelength range. Less than 10 fs pulses are obtained in a few-cycle operating regime. Up to 0.3 mJ output pulse energy with better than 1.5% pulseto-pulse stability at 1 kHz repetition rate is achieved by using a state of the art OPCPA technology.By incorporating parametric amplifier technology together with a novel ultrafast fiber laser helped to create and bring to the market a new tool for femtosecond pump probe, nonlinear spectroscopy,emerging high harmonic generation experiments and other femtosecond and nonlinear spectroscopy applications. With this laser ultrafast science breakthrough is closer to any photonics lab than ever before.
