FemtoTune femtosecond optical parametric amplifier is designed to meet the demanding specifications of modern ultrafast science, while introducing valuable features that enhance measurement efficiency, convenience, flexibility, and reliability.
FemtoTune is based on Ekspla’s extensive experience in developing picosecond and nanosecond tunable systems, as well as optical parametric chirped pulse amplifiers (OPCPAs) with pulse energies up to 1 joule and durations as short as 10 fs. FemtoTune delivers a compact, high-repetition-rate (up to 100 kHz) solution with sub‑50 fs pulse duration across the broad wavelength tuning range, tailored for modern ultrafast spectroscopy and imaging.
The time-synchronised motor positioning enables fast and smooth wavelength tuning, allowing users to scan the full range in just a few seconds or access specific wavelengths within several tenths of a second.
Continuous, gapless tuning in the mid-IR (2.5–10 µm) with a single polarisation eliminates the need to switch between signal and idler waves. This results in faster, more stable measurements ensuring excellent beam pointing stability.
For applications requiring narrow spectral bandwidths, such as SFG or CARS, FemtoTune offers an additional narrowband channel at 1030 nm or 515 nm, providing < 8 cm‑1 bandwidth without the need for complex spectral narrowing techniques. Optical synchronisation with most of our picosecond lasers and wavelength tunable systems allows achieving even narrower bandwidth (< 3 cm‑1) enabling simultaneous high temporal and spectral resolution measurements.
Pumped by robust award-winning industrial-grade FemtoLux series laser, FemtoTune offers long-term stability, hands-free operation, and minimal maintenance.
FemtoTune delivers ultrashort pulses at high repetition rate, enhanced by advanced functionality, all in a compact system.
