Abstract
A laser source for pumping an optical device which requires for its operation a significant amount of light power, the source comprising a semiconductor array (11) for providing a plurality of spaced apart light beams at different wavelengths, an optical assembly (14, 15, 16) for focussing the light beams into an optical waveguide (19), the optical waveguide (19) being coupled to the optical device.
Claims14
A laser pump source for pumping an optical device which requires for its operation a significant amount of light power, the source comprising a semiconductor laser array for emitting a plurality of spaced apart light beams at different wavelengths, and an optical assembly for forming a laser cavity external of said laser array and for focussing the emitted light beams into an optical waveguide, the optical waveguide being coupled to said optical device.
A laser pump source comprising a semiconductor laser array for emitting a plurality of spaced apart light beams at different wavelengths, an optical assembly for focussing the light beams into an end of an optical waveguide, said optical assembly including reflection means for forming a laser cavity external of said semiconductor array so that the light beams emitted by said semiconductor array is reflected to control resonant emission, the reflection means comprising a mirror means coupled to the optical waveguide by coupling means at a point remote from said end of the optical waveguide.
