Abstract

We report on three different variants of a new scalable diode-laser-pumped CW Nd:YAG optical amplifier with a small-signal gain of 19 (13 dB) and output powers of up to 1.5 W at an input power of 600 mW and a pump power of 5.2 W, Due to its compactness, efficiency, and ruggedness, it is well suited for space applications such as free-space intersatellite communications systems. Furthermore, we present a numerical model for the gain of such a multipass amplifier considering the saturation and different losses. This model is in excellent agreement with the measured data. We also show that the signal-to-noise ratio of this system is better than 50 dBc/root Hz and that the amplifier produces nophase noise and is therefore ideal for long-distance coherent communication.
