Abstract
The present invention provides a solid state intra-cavity absorption spectrometer comprising a solid-state gain device interspersed in an array of oscillators in a chamber to produce a wide area coherent high power source of Terahertz radiation. The source is then partitioned into two separate regions, one having a gain medium and one having a sample chamber that can be held a different pressure and is chemically isolated from the gain region thereby forming an intra-cavity absorption spectrometer.
Claims18
An intra-cavity absorption spectrometer comprising:
- a cavity;
- a Terahertz transmissive window splitting the cavity into a sample chamber and a vacuum chamber;
- an array of wave-guide elements disposed in parallel within the vacuum chamber;
- and
- a plurality of solid-state elements interspersed within the wave-guide elements, said solid-state elements oscillating in phase with one another and at the same frequency.
2 more elements
A intra-cavity absorption spectrometer comprising:
- a cavity;
- a Terahertz transmissive window splitting the cavity into two sides, a first side comprising a sample chamber and a second side comprising a vacuum chamber, said vacuum chamber comprising an array of solid-state elements packaged in a specific configurations wherein said elements oscillating in phase with on-e another and at the same frequency.
