Sensitivity of copper bromide vapor brightness amplifier

Abstract

The paper presents the experimental and theoretical evaluation of sensitivity of the copper bromide vapor brightness amplifier (l=50 cm; d=3.2 cm). The research was performed in two experimental modes: Single-Pass brightness amplifier system and the Master oscillator Power Amplifier (MOPA) system. The dependencies of the gain factor (K) and the output signal power (POUT) on the input signal power (PIN) are shown. The input signal power was wearied from 2 μW to 200 mW. The results show that the minimal input signal power, which can be amplified, is (0.001÷0.010) % of ASE power.
