Implication

Experimental study demonstrates a 0.5 dB/km transmission loss in a quartz lens optical beam waveguide, indicating viability for long-distance optical transmission.

Key Points

To measure signal attenuation and evaluate beam energy distribution in an optical beam waveguide utilizing quartz lenses for long-distance optical transmission.
Tested an optical beam waveguide utilizing repeating quartz lenses under varying air pressure conditions along the light path.
Performed photometric measurements to analyze the energy distribution of the transmitted beam and assess mode pattern distortions.
Demonstrated an optical transmission loss of 0.5 dB/km, determined entirely by absorption, scattering, and reflection losses within the quartz lenses.
Observed that transmission loss variation correlates directly with air pressure fluctuations along the optical pathway.
Quantified a launching loss of approximately 0.4 dB, caused predominantly by distortions in the laser beam mode pattern.
