The present invention provides for a device, a method, and a treatment system for chronic disease conditions. The present invention was designed using the theoretical concepts of Quantum Biology. The principles of operation are based on the device's ability to stimulate a Bose-Einstein condensate and excitation of Frolich resonance in living tissue The wavenumbers necessary for this excitation are derived from the solution to the equations for optical phonon scattering in living tissue generated by optical photon excitation. The establishment of this degeneracy condition induces a super conducting state in the tissue. This super conducting state facilitates DNA replication, transcription and translation, thereby allowing the proper formation or regeneration of healthy tissue. This superconducting state provides the conditions necessary for establishing the violation of time reversal invariance in living tissue.

There has been a problem that pumping light leaks from a part having a coating at the joint of a double-clad fiber added with a rare earth and a general single-mode fiber, and heat is generated partly from the fiber by this energy thus causing deterioration of the fiber. Deterioration of a fiber due to residual excitation light can be prevented by preventing residual excitation light in a double-clad fiber from exiting to a single-mode fiber, and the reliability is enhanced. Output of oscillation light can be increased because output of excitation light is not limited. Furthermore, a laser display having a high color reproducibility can be achieved by employing a light source combining a fiber laser light source and a wavelength conversion module.

The present invention relates to a new composition of luminescent matter in which lanthanide cations are incorporated into semiconductor nanocrystals, and methods for making this new composition of matter. The semiconductor nanocrystal structure serves as an antenna for allowing the excited electronic states of the semiconductor nanocrystals to sensitize lanthanide cation emission. In comparison to organic antenna types, semiconductor nanocrystals are able to protect lanthanide cations from quenching solvent molecules without supplying high energy vibrations, thereby resisting non-radiative deactivation of the lanthanide cation excited states. Semiconductor nanocrystals have several advantages as species that absorb and emit photons, namely, broad absorbance bands with high epsilon values and emission wavelengths that can be easily tuned through their size, which is controlled through synthesis conditions. Lanthanide cations also have several advantages—sharp emission bands and long luminescence lifetimes.
