TL;DR: In this paper, the nonlinear material proustite (Ag3 AsS3) has been employed in an optical parametric oscillator, which is pumped by the 1.06μ output from a repetitively Q•switched Nd : YAG laser and has signal and idler outputs near 2.1μ.
Abstract: The nonlinear material proustite (Ag3 AsS3) has been employed in an optical parametric oscillator. The oscillator is pumped by the 1.06‐μ output from a repetitively Q‐switched Nd : YAG laser and has signal and idler outputs near 2.1μ. Operation of the oscillator is described and the results of optical parametric fluorescence experiments are given. The primary limitation on the operation of the oscillator is surface damage to the proustite crystal.

TL;DR: In this paper, the authors studied the effect of a parametric amplifier on the intensity squeezing of a three-level laser with a three level cavity and found that the effect is to increase the intracavity squeezing by a maximum of 50%.
Abstract: We seek to analyze, employing stochastic differential equations, the squeezing and statistical properties of the light generated by a three-level laser whose cavity contains a parametric amplifier. It is found that the effect of the parametric amplifier is to increase the intracavity squeezing by a maximum of 50%.

TL;DR: In this article, a non-degenerate parametric amplifier with state discrimination was used to detect quantum jumps of a transmon qubit with a fidelity of 90% of state discrimination.
Abstract: Determining the state of a qubit on a time scale much shorter than its relaxation time is an essential requirement for quantum information processing. With the aid of a nondegenerate parametric amplifier, we demonstrate the continuous detection of quantum jumps of a transmon qubit with $90\mathrm{%}$ fidelity of state discrimination. Entirely fabricated by standard two-step optical-lithography techniques, this type of parametric amplifier consists of a dispersion-engineered Josephson-junction (JJ) array. By using long arrays, containing ${10}^{3}\phantom{\rule{0.2em}{0ex}}\mathrm{JJs}$, we can obtain amplification in multiple eigenmodes with frequencies below $10\phantom{\rule{0.2em}{0ex}}\mathrm{GHz}$, which is the typical range for qubit readout. Moreover, if a moderate flux tunability of each mode is introduced, employing superconducting-quantum-interference-device junctions, a single amplifier device could potentially cover the entire frequency band between 1 and 10 GHz.
