Terahertz light has huge potential to enable innovation and improve upon existing photonic solutions in a variety of sectors. Despite the proliferation of applications for THz imaging, the number of commercially available terahertz imaging systems is limited. Access Laser’s wavelength and frequency stabilized IR lasers allow for optical pumping of a variety of gaseous mediums that can produce THz radiation with average power that is orders of magnitude higher than solid-state lasers, non-linear crystal conversion, or frequency mixing typically found in this market space.
Common challenges Access Laser systems solve:
- Provide true terahertz light beyond the 300 gigahertz limit commonly claimed by solid-state suppliers
- Achieve average power greater than the typical microwatt provided by frequency mixing diode sources
- Versatile wavelength production by changing the gas which is optically pump by a longwave infrared laser
- Stable, robust operation to take your experiment from research into development
There are numerous processes that occur in the far-infrared (FIR) region of the light spectrum that have not been directly studied due to a lack of FIR light sources with power in the milliwatt to watt range. While recent research and development efforts have been focused on ultrashort FIR pulses, referred to as THz pulses (0.1 to about 6 THz), the full potential of this wavelength is just beginning to emerge.
- Average power of 1W at 2.54THz
- Enables new research in FIR Spectroscopy
- Time Domain measurement of material boundaries
- Frequency Domain inspection of material absorption
- Non-Ionizing complementary 2D Imaging
- Continuous Wave or Pulsed operation
- True terahertz light beyond the gigahertz domain
- Wavelength-, frequency- and power-stabilized pump sources
