Abstract: A method is disclosed for irradiating a biological sample with far infrared (FIR) irradiation, including providing tunable FIR irradiation, removing X rays from the irradiation, and irradiating at least one biological sample with the tunable FIR irradiation, wherein at least a component of the biological sample undergoes at least one of a conformational change or a phase change in response to the irradiating. An FIR irradiation device is disclosed, including an FIR source producing an FIR irradiation having a tunable wavelength, the source being capable of continuous-wave output, and a filter receiving the irradiation from the source.

Abstract: The present disclosure is directed to laser apparatuses for generating coherent electromagnetic laser radiation having an electron beam generator, a diffraction grating element oriented such that a beam of electrons from the electron beam generator is directed over the diffraction grating element, and at least one wing element coupled to the diffraction grating element. In some embodiments, the wing element(s) can be coupled to a top portion of the diffraction grating element. While in others, the wing element(s) can be coupled to a side portion of the diffraction grating element. The present disclosure is also directed to methods of manufacturing diffraction grating elements involving placing at least one secondary conducting sheet having a first height on at least one primary conductive sheet having a different second height, and securing the primary and secondary conductive sheets together. The primary and secondary conductive sheets can be alternating and their thicknesses may also be different.
