News: The Tricolor Multi-Wavelength Laser System                                                      

Avesta has introduced the Tricolor, which is a novel multi-channel femtosecond laser source providing three inherently synchronized ultrafast outputs at 1050, 800 and 525 nm simultaneously. Time-resolved experiments have just become much simpler. Further details are provided here at the product's page.

News: 150-ps response time for a THz detector measured with TERA-AX                    

Our partners at "Terasense" have used our TERA-AX high-energy THz pulsed generator to precisely measure the ultrafast response time of their proprietary passive THz detector. Such short response time opens up the possibility to observe and resolve ultrafast transient processes in many THz applications. Click here for more details about the experiment, information about the TERA-AX may be found here.

News: ASP-IR spectrometer family updated, range up to 3.5 um                                 

Our engineers have recently updated the specifications of the ASP-IR family of our scanning spectrometers, introducing the new ASP-IR-3.5 model, which is capable of spectral measurement up to 3450 nm. Further details may be found here.

News: 10-TW commercial system released                                                                   

We are proud to release our commercial Ti:S femtosecond system with the pulse peak power over 10 TW (pulse energy 500 mJ at <50 fs). The AVET-10 system is designed to fulfill the demand for research in particle acceleration, x-ray and attosecond pulse generation, plasma and fusion studies and many other areas.

News: FREGAT-200 Cr:F amplifier installed in Kyoto University                                    

Avesta and Tokyo Instruments have successfully installed its Cr:Forsterite amplifier system in Kyoto University along with Avesta's ASF single-shot autocorrelator. The amplifier delivers >200 uJ pulses @1KHz @1238 nm. You can find out more details and view test data on the FREGAT description page.

Featured Article: Farewell to contrast!                                                                          

Two is a company; three is a crowd! And the third pulse that appears on exit is strangely in front!
    It is time to purchase the new COMET contrast measurement system to see how a weak post-pulse hiding behind the main powerful pulse gives birth to a third pulse in front of the main one.
