Abstract
A laser beam for improved atmospheric penetration is produced by a device having two or more laser sources each producing a laser beam of a different wavelength. The beams are combined by an optical combiner into a composite beam having at least two wavelengths, so that the different properties of the different wavelengths may combine to improve atmospheric penetration.
Claims21
A device comprising:
- a first laser source configured to produce a laser beam of a first wavelength;
- at least a second laser source configured to produce a laser beam of a second wavelength;
- an optical combiner configured to combine the first and at least the second laser beams into a beam structure in which said beam of said first wavelength surrounds said beam of said second wavelength thereby to provide a single composite beam having at least two wavelengths, one of said wavelengths being selected to heat the atmosphere along the length of the beam to cause moisture and dust to dissipate and create a path for the beam of the second wavelength.
A device comprising:
- a first laser source configured to produce a laser beam of a first wavelength;
- at least a second laser source configured to produce a laser beam of a second wavelength;
- an optical combiner configured to combine the first and at least the second laser beams into a beam structure in which said beam of said first wavelength surrounds said beam of said second wavelength thereby to provide a single composite beam having at least two wavelengths, one of said wavelengths being selected for absorption in the atmosphere causing moisture and dust to dissipate and create a path for the beam of the second wavelength.
A device comprising:
- at least one laser source configured to produce a laser beam of a first wavelength, the wavelength selected to exert a first, absorption effect on the atmosphere;
- at least a second laser source configured to produce a laser beam of a second wavelength selected to exert a second, absorption effect on the atmosphere, the second absorption effect being lower than the first absorption effect;
- and
- an optical combiner configured to combine the first and at least the second laser beams into a beam structure in which said beam of said first wavelength surrounds said beam of said second wavelength thereby to provide a single composite beam having at least two wavelengths to produce a composite effect on the atmosphere, the first wavelength selected to heat the atmosphere along the length of the beam causing moisture and dust to dissipate and create a path for the beam of the second wavelength.
