Low Frequency Pump-Based Intracavity Cascade Parametric Amplification
Intracavity cascade parametric amplification with low frequency pump is a technique to enhance the signal amplification in an optical cavity with the help of low frequency pump source. The method we present is that of which combines total amplification with preservation of signal quality we note that we use a series of parametric gain elements which we have arranged in a cascaded structure within the cavity. We see that by means of the intracavity set up we enable for large scale interaction between the pump and the signal waves which in turn we see results in an improved performance in terms of gain and reduced noise. This technique we find is very well put to use in high end applications such as precision sensing and quantum optics that which require extreme sensitivity and low noise. In the paper we also present the results which display how this method improves the field of optical amplification.
