Abstract

Recently, using an aopposite injection we have introduced a novel laser injection-locking approach for high gain (~10⁴-10⁸) and linear amplification of modulated low power (~μW-mW) laser radiation. In this work we report the investigation of the noise characteristics of such amplifier at the example of high repetition rate pulse pumped linear dye lasers. The background emission of the laser at the laser modes outside the signal and counter injection wavelengths is considered as a main source of the noise. By modeling the laser action with adapted system of differential equations and numerical analysis, solving this system for the cavity modes, we have obtained the total noise and its spectral distribution. The results show that for suitably chosen conditions the intracavity noise is very low or acceptable (~10^-2 with respect to the signal output). The essential dependencies of noise characteristics from the system parameters are carried out.
