1. A method for chasing animals away from a surface the animals are traversing, the method comprising subjecting the surface to a fixed laser beam having a wavelength selected from between approximately 4.000 and 7.500 Angstroms and wherein the laser beam is positioned between approximately 8 and 24 inches above the surface so as to effect a laser swath parallel with the surface. 2. The method as recited in claim 1, wherein the surface is defined by a body of water. 3. The method as recited in claim 1, wherein the laser beam has a wavelength selected from between approximately 6450 and 6650 Angstroms. 4. The method as recited in claim 1, wherein the laser beam has an intensity of at least 20 μW/cm2at 400 meters from a light beam source. 5. The method as recited in claim 1, wherein the laser beam is emitted with a swath of approximately 90°. 6. The method as recited in claim 1, wherein the surface is subjected to a plurality of laser beams. 7. The method as recited in claim 1, wherein the animals are water fowl, the surface is the surface of a water body, and the water fowl are swimming on the surface. 8. A method for keeping animals from a surface, comprising subjecting the animals to a fixed visible laser beam swath positioned between approximately 8 and 24 inches above the surface so that the swath is parallel with the surface. 9. The method as recited in claim 8, wherein the surface is defined by a body of water. 10. The method as recited in claim 8, wherein the laser beam swath has an intensity of at least 20 μW/cm2where the animals are located. 11. The method as recited in claim 8, wherein the laser beam swath spans approximately 90°. 12. The method as recited in claim 8 wherein the animals are located within the laser beam swath. 13. The method as recited in claim 8, wherein the laser beam swath is visible by the animals. 14. A method for disturbing nocturnal nesting areas of waterfowl, said method comprising: a) selecting a nocturnal nesting area; and b) subjecting said nocturnal nesting area to a single-wavelength laser beam swath wherein the laser beam is positioned between approximately 8 and 24 inches above a water surface near the nesting area so as to effect a laser swath parallel with the nesting area. 15. The method as recited in claim 14, wherein the laser beam swath has a wavelength of between approximately 4,000 and 7,000 Angstroms. 16. The method as recited in claim 14, wherein the laser beam swath has an intensity of at least 20 μW/cm2at 400 meters from a light. 17. The method as recited in claim 14, wherein the laser beam swath is emitted within an angle of approximately 90°. 18. The method as recited in claim 14, wherein the laser beam swath is activated at dusk. 19. The method as recited in claim 14, wherein the laser beam swath is emitted from a fixed source.
