Terahertz Parametric Oscillator

TPO - 1500

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.

TPO - 850

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.

THz Generators

QS1-260 based THz sources:
Operating frequency range of QS1-260 (160-260 GHz) can be extended to 2100GHz, using frequency multipliers. Typical maximum power across different ranges is shown in the table below.

QS1-260-2100-HP

Notes: Operation of QS1-260 based sources requires VR-6M power supply, MS-X.X magnetic system and BWO water cooling system.

QS1-370 and QS1-710 based THz sources:
Operating frequency range of QS1-370 (180-370 GHz) can be extended to 1150 GHz, using frequency multipliers. A frequency tripler designed QS1-710 BWO extends operation of this source to 1800-2100 GHz range.Typical maximum power across different ranges is shown in the table below.

Notes: Operation of QS1-370 and QS1-710 based sources requires VR-6M power supply, MS-X.X magnetic system and BWO water cooling system.

Other THz sources:
BWO listed in the table below offer high power across frequency ranges specified below. However, there are no frequency multipliers that can be used on this BWOs to extend their spectral coverage. Typical maximum power across different frequency ranges is shown in the table below.

QS2-180 based THz sources:
Operating frequency range of QS2-180 (100-180 GHz) can be extended to 1500 GHz, using frequency multipliers. Typical maximum power across different ranges is shown in the table below.

QS2-1500-HP

Notes: Operation of QS2-180 based sources requires VR-3M power supply.

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
