The UltraFlux FT031k from EKSPLA is a Tunable Femtosecond Laser System with a wavelength from 700 to 1010 nm. It delivers an output pulse energy of up to 300 µJ with a pulse duration of 35-60 fs and a repetition rate of up to 1 kHz. This linearly/horizontally polarised laser system provides a Gaussian beam with a diameter of 2 mm and has beam-pointing stability of up to 1.5% RMS for over 12 hours.
The UltraFlux FT031k is based on the novel OPCPA (Optical Parametric Chirped Pulse Amplification) technology that uses a picosecond fiber laser for seeding both the picosecond DPSS pump laser and femtosecond parametric amplifier by spectrally broadening the output. This eliminates the need for pump and seed pulse synchronization and also increases the contrast of the output pulses in the picosecond to the nanosecond time scale. It is available in a module that measures 1.20 x 0.75 m and is suitable for high harmonic generation, non-linear spectroscopy, femtosecond pump-probe spectroscopy, broadband CARS, and SFG applications.
