NEWS: World of Photonics 2011 Show in Munich                                                            

   Avesta would like to thank the visitors of our booth at the LASER 2011 World of Photonics Show in Munich (23-26 May). Hope to see you again next time.

NEWS: New PErL ultrafast compact OEM fiber laser is now available                            

   The PErL ultrashort-pulse fiber laser is a new OEM-oriented product from Avesta. It features ultra-compact design while still delivering 50 mW of average power at 1560 nm. Available pulse durations start from 250 fs and go up to 5 ps. Only a +5 V supply is necessary for driving the unit, all control and supply electronics are built into the device's body. See detailed specification here.

NEWS: AA-M autocorrelator for microscopy is now available                                        

   The new AA-M scanning autocorrelator with one internal and one external photodetectors is now available. The system provides easy measurement at input and sample position of a microscope allowing to determine the pulse duration broadening due to optics' dispersion. More details can be found here.

NEWS: New Yb amplifier system TETA                                                                             

   Avesta introduces the new regenerative Yb-based compact amplifier system TETA designed for industrial and scientidfic application. The amplifier delivers uJ-level pulses with repetition rate up to 20 kHz. The system is an ideal choice for materials processing and micromachining applications. Please find out more details here.

NEWS: New prism pulse compressor APC                                                                        

   The new prism pulse compressor APC offers versatile control over dispersion of femtosecond pulses that is necessary in various spectroscopic applications where there are optics which introduce unwanted dispersion resulting in pulse broadening at the sample. Please visit the product page here for more details.

NEWS: New IR autocorrelator for OPA pulse measurement                                            

   Avesta has developed the new IRA-3-10 scanning autocorrelator for measurement of 30 fs to 50 ps pulses at 3-10 µm wavelength range.  Please click here to vie w the product's page.

NEWS: LabView driver for the ASF single-shot autocorrelator                                       

   Avesta's engineers offer new LabView driver for the ASF single-shot autocorrelator for all new purchases. Stand-alone version is also included for greater flexibility and control. Just a reminder: OG pulse pickers also feature full LabView integration and stand-alone drivers.

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.

NEWS: New scanning autocorrelator AA-20DD                                                                

   Avesta has introduced the AA-20DD scanning autocorrelator that is able to measure pulses from 20 fs to 6 ps (@450-2000 nm) and has USB interface to connect the unit to a PC. The user-friendly software is provided with the device to offer several useful tools for pulse duration measurement and observation.

NEWS: New Yb-doped solid-state femtosecond laser                                                     

    Avesta has introduced a new Yb-doped solid-state femtosecond laser TeMa-1058 having 1058 nm wavelength and <150 fs pulses. The laser operates at 80 MHz repetition rate and produces >400 mW of average output power. The built-in diode pump module ensures trouble-free and robust operation.

NEWS: 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.
