High-power signals optical generator for telecommunication systems

An optical signal generator comprising:

• a continuous wave coherent optical signal source and an optical amplifier operatively connected to said source for amplifying optical signals received by said optical amplifier from said source;
• said source comprising an optical fiber laser oscillator including a first active optical fiber having a core doped with a fluorescent substance, said fluorescent substance having laser emission at an emission wavelength and light absorption at a pumping wavelength different from said emission wavelength;
• said optical amplifier comprising a second active optical fiber having a core doped with a fluorescent substance having laser emission at said emission wavelength and light absorption at said pumping wavelength;
• a source of pumping optical power at said pumping wavelength operatively connected to at least one of said first and said second active optical fibers for supplying pumping optical power to said at least one of said first and second active fibers;
• and
• selective transfer means for said pumping optical power, said transfer means being operatively connected to said first and said second active optical fibers to transfer non-absorbed optical power at said pumping wavelength from one of said first and second active optical fibers to the other of said first and second active optical fibers.
