The TiC CW tunable laser is the choice with applications where tuning range and high average power level are a must, such as spectroscopy, semiconductor research and many more. The laser system features titanium-sapphire active medium for obtaining broad tuning range of 700 to 1000 nm with linewidth of <45 GHz. The system is equipped with a birefringent Lyot filter for manual or USB-controlled wavelength tuning*. Optional thick and thin automated etalons can be installed into the resonator cavity to bring the linewidth down to <2 GHz. Windows PC software is provided with the laser system for easier tuning and calibration. Learn more... |  |

AMPLIFIERS
The REUS family of amplifiers comprise a femtosecond seed oscillator (TiF-20F or fiber EFOA-SH), stretcher, Faraday isolator, Pockels cell with control and synchronization unit, regenerative amplifier, pulsed amplifier pump laser and compressor. The system may be equipped with an additional Pockels cell for contrast improvement. The cell enables the user to get "pulse-on-demand" operation and reduce the repetition rate to the required values. All elements are gathered into a single box on a thick breadboard, thus providing reliable and stable generation and hands-free operation. Learn more…

The MATEKO femtosecond amplifier is designed to provide mJ-level output by amplifying pulses from a Ti:S or fiber ultrafast seed oscillator. The amplification ratio in such a system is more than 10^6 and happens in a Ti:S crystal during several passes while pumping by a Q-switched 515-532 nm laser. The hybrid system comprises two amplifiers: a regenerative stage and a multipass stage, thus enabling higher pulse energies. A single pump laser is used to pump both stages which reduces the cost of the system and boosts stability and performance. Learn more… |  |

The Comet third-order scanning cross-correlator (aka TOCC) offers its 10^10-wide dynamic range and 950ps-broad temporal range at your service. It can give comprehensive information about the ASE of the amplifier, pulse pedestal, pre-and post-pulses's structure and shape. The unit also gives information about the pulse intensity cross-correlation function and measure pulse duration and shape. The user can also select the desired narrow area (say, +/- 50 ps from the peak) for faster scanning speed. The Comet communicates with a PC via USB and acquisition and analysis software is included in the package. Learn more... |  |
The Comet-A cross-correlator is specifically developed for measurement of pulse duration of femtosecond and ps OPAs. Knowing exact pulse duration and pedestal information is essential for many applications, especially with the OPAs as there are quite few devices that can fulfill the task. The advantage of the cross-correlation method is that it can display pre- and post-pulse structure while autocorrelation will show symmetric curve. However, if you require higher resolution, please refer to our IRA-3-10 autocorrelator for IR measurements. Learn more... | |
