Abstract

Recently we have proposed an injection-locking technique for all-optical and high gain (approximately 10³ - 10⁶) amplification of a periodically modulated (PM) intensity low power (approximately μW) laser radiation. The amplification is based on the injection locking control in linear laser schemes with homogeneously broadened active medium. The problem that limits use of such type of optical amplifier is to obtain a linear response to the PM injection. This is solved using a competitive CW injection. We have introduced a few different solutions of such laser amplifier -- with pulse pumping and with CW pumping, using the high repetition rate intracavity laser generation chopping. Here we report the detailed comparative study of such different realization of the proposed by us technique. The theoretical study is based on adapted rate equations system. The main results concerned the optimal case with the lowest nonlinear distortion and the condition of its elimination.
