Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A coherent light power source, comprising: a pumping laser for emitting first and second beams of light at a first wavelength; a coherent signal source for emitting a third beam of light at a second wavelength; and an amplifying optical fiber for receiving said first beam of light emitted by said pumping laser and said third beam of light emitted by said coherent signal source, wherein said second beam of light at said first wavelength is received by said coherent signal source and said third beam of light at said second wavelength is received by said amplifying optical fiber through said pumping laser which is transparent to said third beam of light.
Claim 2
Dependent Claim
112 words
A coherent light power source, comprising: a pumping laser for emitting first and second beams of light at a first wavelength; a coherent signal source for emitting a third beam of light at a second wavelength; and an amplifying optical fiber for receiving said first beam of light emitted by said pumping laser and said third beam of light emitted by said coherent signal source, wherein said second beam of light at said first wavelength is received by said coherent signal source and said third beam of light at said second wavelength is received by said amplifying optical fiber through said pumping laser which is transparent to said third beam of light.
Claim 3
Dependent Claim
38 words
The coherent light power source according to claim 1, wherein the pumping laser emits said third light beam to said coherent signal source in a direction parallel to said second light beam emitted by said coherent signal source.
Claim 4
Dependent Claim
31 words
The coherent light power source according to claim 2, wherein said coherent signal source receives said third light beam from a direction opposite to the direction of said second light beam.
