Claims
- 1. A method for pumping a lasing material with a light beam having a spatial cross-sectional distribution which is extended predominantly in one direction, the method comprising:
- receiving the light beam;
- redirecting different portions of the received light beam to different locations on an imaginary plane wherein at least two portions of the light beam are directed along two non-parallel paths so as to generate a two-dimensional pattern of light on the imaginary plane;
- redirecting portions of said two-dimensional pattern of light to a point along an axis of the lasing material.
- 2. A method for pumping a lasing material with a linear array of individual light beams, the method comprising:
- receiving the linear array of individual light beams;
- redirecting each individual light beam to different locations on an imaginary plane wherein at least two light beams of the linear array of individual light beams are directed along two non-parallel paths so as to generate a two-dimensional pattern of light beams on the imaginary plan;
- redirecting the light beams of the two-dimensional pattern of light beams to a point along an axis of the lasing material.
- 3. A method for pumping a lasing material with a two-dimensional light beam, the method comprising:
- receiving the two-dimensional light beam;
- redirecting different portions of the received two-dimensional light beam to different locations on an imaginary plane wherein at least two portions of the two-dimensional light beam are directed along two non-parallel paths so as to generate a two-dimensional pattern of light on the imaginary plane, the two-dimensional pattern of light being a non-image of the two-dimensional light beam;
- redirecting portions of said two-dimensional pattern of light to a point along an axis of the lasing material.
- 4. A method for pumping a lasing material with a two-dimensional array of individual light beams, the method comprising:
- receiving the two-dimensional array of individual light beams;
- redirecting each of the received light beams of said two-dimensional array of individual light beams to different locations on an imaginary plane wherein at least two light beams of the two-dimensional array of individual light beams are directed along two-non-parallel paths so as to generate a two-dimensional pattern of light beams on the imaginary plane, the two-dimensional pattern of light beams being other than a non-image of the two-dimensional array of light beams;
- redirecting the light beams of said two-dimensional pattern of light beams to a point along an axis of the lasing material.
