Amplification in Fabry-Perot type semiconductor laser amplifiers has been observed with a directly coupled laser-amplifier pair. Amplifier gain as a function of amplifier injection current was measured and compared with theoretical models. Regarding F-P type semiconductor laser amplifier as a photodiode
the optical coupling efficiency between amplifier and laser can be measured by the short photocurrent of laser amplifier.
