TL;DR: In this article, an analysis of the coupling of the quantum fluctuations of two initially independent laser beams, using a two-photon non-linear medium inside an optical cavity, is presented, where depending on the detuning of the lasers relative to the cavity resonance, either quantum non-demolition measurement, or squeezing of the sum or difference of the input intensities can be obtained.

Abstract: A laser system for producing pulsed, longitudinal mode optical energy over a widely tunable range of wavelengths. The system includes an optical cavity and a solid-state gain medium. The optical cavity comprises first, second, and third optical element means. The first optical element means reflects energy received along a first reflective optical axis and directs the energy toward the second optical element means, which diffracts the optical energy into at least two orders of interference. The energy diffracted according to a first order of interference is reflected back toward the second optical element means by a third optical element means, thereby creating a resonant optical cavity. Another portion of the optical energy diffracted by the second optical element means is produced as an output beam. The solid-state gain medium is located on the optical axis between the first and second optical element means and receives pump energy from a plurality of pump beams that are within two degrees of being colinear with the first reflective optical axis. The solid-state gain medium converts the pump beam energy to optical energy having a desired wavelength with a very high efficiency, without required pump beam energy densities above a predetermined level. The laser system is tunable by moving the third optical element means with respect to the second optical element means, thereby causing optical energy at a tunable wavelength to resonate within the optical cavity.

TL;DR: In this article, the authors proposed a novel surface-emitting semiconductor laser with a wavelength-resonant periodic gain medium, which has performed significantly better than conventional double-heterostructure and multiple-quantum-well vertical-cavity devices.
Abstract: Recently, we have demonstrated a novel surface-emitting semiconductor laser with a wavelength-resonant periodic gain medium, which has performed significantly better than conventional double-heterostructure and multiple-quantum-well vertical-cavity devices. The gain medium consists of a series of half-wave-spaced quantum wells which provides enhanced longitudinal gain at a selected wavelength in the vertical direction, reducing transverse amplified spontaneous emission, lowering the threshold and raising the quantum efficiency. However, because the antinodes of the standing-wave optical field must coincide with the quantum wells, considerable attention must be devoted to designing the vertical cavity. Here we examine various cavity configurations in which the wavelength-resonant periodic gain medium has been incorporated. Multilayer epitaxial reflectors are particularly attractive for fabricating monolithic vertical-cavity surface-emitting lasers.
