|* - <100 fs @ 20 mW or <50 fs @ 10 mW specs upon request;
** - pulse duration (T) and output power (P for EFOA) should be selected with your request. For the EFOA model, the (lowest available pulse duration)/(highest available average power) relation is equal to 1 (i.e. at 100 fs the highest possible power is 100 mW, at 250 fs - 250 mW etc); average power up to 5 W upon request;
*** - please specify with your request.
Fiber-based femtosecond lasers offer robust and stable operation without the need for constant realignment. The low cost and stability of fiber-based femtosecond lasers mean that even beginner research labs can have a femtosecond pulse source without the need for expensive or complicated equipment. This brings ultrafast research into the realm of undergraduate and other educational environments. With pulse lengths of 100 fs at 1550 nm fiber femtosecond lasers can also be used as seed sources for femtosecond fiber amplifiers. The 1550 nm wavelength of Er-doped fiber lasers also makes them an attractive tool for ultrahigh-speed optical communications applications.
The second harmonic version EFOA-SH with wavelength 780 nm is also available.

Avesta’s facilities will be closed for the New Year break from 30 Dec 2017 till 08 Jan 2018. We will resume all operations on 09 Jan 2018. However, we hope to provide periodic e-mail correspondence during the holidays. We wish you a fruitful and prosperous Year 2018!
Avesta is participating in the “LASER World of PHOTONICS 2017” (Munich, Germany, 26-29 June 2017) trade show. Feel free to drop by our booth B2.151 to see the TeMa Yb laser system along with the AA-20 autocorrelator and GECON supercontinuum generator. The trade show participation is supported by the Russian Export Center and organized by Expocenter and Russian Laser Association.
