The TETA is an Yb solid-state laser system. The system comprises a built-in fiber seed oscillator, fiber pulse stretcher, Faraday isolator, CPA-based regenerative amplifier with direct diode pumping, additional pulse picker and pulse compressor. All components are integrated into a single thermostabilized box ensuring stability and true turn-key operation. The additional built-in Pockels cell offers instant output radiation shuttering as well as total user control of output repetition rate. Moreover, the cell features precise pulse picking with control over the number of fired pulses (burst mode) and temporal period of radiation. The TETA system may be equipped with a SH and FH generation units, as well as with the Compulse capillary compressor which allows to bring the pulse duration down to 30 fs with >50% energy conversion efficiency.
The TETA laser system is a reliable and flexible radiation source for femtosecond micromachining systems, terahertz imaging, OPA pumping, remote sensing and ultrafast spectroscopy.

Dear colleagues, Avesta will be upgrading this corporate web-site starting 04 Nov 2017. Please note that you might experience some turbulence while browsing the web-site in the process. We hope to finish the upgrade as soon as possible to introduce new looks, updated products and more information.
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.
