High Q Laser introduces the ultra compact femtoREGEN™ UC – an all-in-one femtosecond regenerative amplifier - delivering 2 W power at 200 kHz repetition rate with 350 fs pulse duration on a footprint of 34 cm x 78 cm. The system presents industrial reliability and robustness and can be customized to an OEM integrator's needs for medical, industrial and scientific applications such as tissue engineering and nano processing. It is based on the high end Yb-doped laser materials and utilizes High Q Laser's Intra-Cavity-Chirped-Pulse-Amplification (ICCPA) for ultra compact design.
The femtoREGEN UC, which comprises the resonator of the regenerative amplifier and the Pockels cell in one monolithic module, integrates all pump laser diode modules, the seed oscillator and the amplifier in a single ultra compact housing. The seed laser is designed as a High Q Laser ultra compact (UC) module itself for high stability and compactness. The UC seed oscillator is operating with "de-rated" nominal pump current for longest MTBF and is based on High Q Laser's patented resonator folding technique withstanding a 50 g shock test for most robust performance. The semiconductor saturable absorber mirror (SESAM) provides passive and self-starting mode locking for high temporal stability.
Customers benefit from the ongoing OEM production in quality, performance and investment cost. The high modularity ensures high temporal and spatial stability as well as easy service and maintenance resulting in low operation cost and high MTBF.
The femtoREGEN has applications in various markets, including:
Semiconductor: Mask repair, nano scale thin film ablation, waveguide writing, direct write lithography
Medical/Life Sciences: "Cold Ablation" of biological tissue in ophthalmology and neurology, femtosecond laser dissection, cell nano manipulation
Research: Ultrafast spectroscopy together with our High Q Laser wavelength conversion system (harmonics generation, OPA), non linear optics
Nano Processing: Laser ablation for most precise material ablation or changes, e.g. photovoltaics, flat panel display repair
