The UltraFlux FT300 Series from EKSPLA are Tunable Wavelength Femtosecond Laser Systems that operate from 210 to 1010 nm. They are based on the novel OPCPA (Optical Parametric Chirped Pulse Amplification) technology - for simple and cost-efficient operation and have a patented front-end design (patents no. EP2827461 and EP2924500). These systems have a pulse energy of 3 mJ with a pulse duration of up to 60 fs and a pulse repetition rate of up to 1 kHz. They have a beam pointing stability of less than 50 µrad and features a PLL for (<1 ps, RMS) locking with external synchronization pulse.
The femtosecond laser systems incorporate the advantages of ultrafast fiber laser, solid-state, and parametric amplification technologies. Novel 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 the femtosecond regenerative amplifier and eliminates the need of pump and seed pulse synchronization. In addition to that, the contrast of the output pulses in the picosecond to nanosecond time scale is potentially increased.
This series is assembled on a rigid breadboard to ensure excellent long-term stability. The modular internal design offers a high level of customization and easy scalability. These systems can be customized according to customer requirements. These laser systems are ideal for broadband CARS and SFG, femtosecond pump-probe spectroscopy, nonlinear spectroscopy, and high harmonic generation.
