Terahertz Parametric Oscillator

TPO - 1500

tpo21

TPO-1500 is based on difference frequency generation in quasi-phase matched GaAs crystal placed inside an optical parametric oscilator (OPO) pumped by an ultrafast fiber laser. If generates 6-10 ps THz pulses at repetition rate of 110 MHz, delivering 0.1mW of average and more than 150 mW of peak power. Central wavelength of 1.5 THz and spectral width of 100 GHz fits perfectly into one of the atmospheric transmission windows, making this source ideal for THz imaging application. High peak power makes TPO-1500 suitable for imaging systems employing non-linear optical effects, while sufficiently high average power makes it suitable for thermal detector array imaging as well.

For more information, dowload the datasheet.

TPO - 850

tpo21

TPO-850 is based on difference frequency generation in quasi-phase matched GaAs crystal placed inside an optical parametric oscilator (OPO) pumped by an ultrafast fiber laser. If generates 6-10 ps THz pulses at repetition rate of 110 MHz, delivering 0.1mW of average and more than 140 mW of peak power. Central frequency of 850 GHz and spectral width of 100 GHz fits perfectly into one of the atmospheric transmission windows, making this source ideal for THz imaging application. High peak power makes TPO-850 suitable for imaging systems employing non-linear optical effects, while sufficiently high average power makes it suitable for thermal detector array imaging as well.

BWO Power Supplies:

VR-series power supplies provide for highly stabilized cathode voltage ranging from 0 to 6000 V, as well as BWO grid and heater voltages.

The software package (“EPSILON”) and digital-to-analog converter (DAC-16) enable user-friendly control of the system via RS-232 or GPIB interfaces.

BWO Magnets:

The MS-X.X magnetic systems are designed to house high frequency BWO's operating in the spectral range 0.18 - 1.42 THz. The systems include a permanent magnet with inputs for BWO electrical connections and the water cooling system. The MS-1.2 and MS-1.3 models are also equipped with a 2-axis mechanical rotation stage for centering the BWO in the magnetic field.

Model # Magnetic Field (Tesla) Size (inches) Weight (lbs) Designed for
MS-0.6 0.6 7 x 7 x 7 30 QS1-260
MS-0.7 0.7 9 x 9 x 9 60 QS1-370
MS-1.3 1.3 12 x 12 x 12 110 all models
