• Product Brief

FEMTOLASERS Produktions GmbH
is the premiere manufacturer of ultrafast, compact and reliable laser oscillator and amplifier solutions, generating optical pulses down to 7 fs with megawatt and multi-gigawatt peak powers at MHz and kHz repetition rates.
FEMTOLASERS is a spin-off of Vienna's University of Technology and is well integrated in the academic community with a broad network of dedicated scientists. During the past few years, no other company has been able to develop and successfully manufacture ultrafast lasers with such outstanding parameters in the femtosecond regime.

Founded in 1994 in Vienna, Austria, the company's innovative products and excellent services have evolved to be the first choice among OEMs and scientists worldwide for demanding applications and solutions. FEMTOLASERS state-of-the art products offer technology of highest quality providing reliable, adaptable and easy to use femtosecond lasers.
CEP generations 1-4
A decade ago, FEMTOLASERS decided to make the development of Carrier Envelope Phase (CEP) stabilized oscillators and amplifiers a key topic. In retrospect, it must be acknowledged that the CEP decision was not just courageous, but also farsighted. By developing a family of ultrafast lasers with CEP stable output pulses, the company landed its biggest success story: The break through into the attosecond-era. Not only being the indisputable leader in CEP stabilized ultrafast oscillators and amplifiers, FEMTOLASERS is the only manufacturer capable of supplying reliable and high quality CEP stabilized ultrafast laser systems. Our pioneering spirit continuously boosts performance and reliability of the CEP stabilized ultrafast laser systems, which is manifested by currently employing CEP3 (the 3rd CEP generation). Products from alternative manufacturers still rely on CEP1 (1st generation) dating back to FEMTOLASERS early days in CEP, a decade ago.
