    The TETA femtosecond amplified laser system comprises a fiber seed oscillator, Pockels cells with a control and synchronization unit, and a diode-pumped regenerative amplifier. All the components are integrated into a single box providing increased stability and trouble-free 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 laser system is a reliable and flexible radiation source for femtosecond micromachining systems, terahertz imaging, OPA pumping, remote sensing and ultrafast spectroscopy.
