Squeezed states of light has played a crucial role in the development of quantum physics
We investigate the steady-state analysis of the squeezing and statistical properties of the light generated by a coherently pumped degenerate three-level laser with open cavity which is coupled to a two-mode vacuum reservoir via a single-port mirror
Unlike the mean photon number, the quadrature squeezing does not depend on the number of atoms
Summary
Squeezed states of light has played a crucial role in the development of quantum physics. Fesseha [29] has studied the squeezing and the statistical properties of the light produced by a degenerate three-level laser with the atoms in a closed cavity and pumped by electron bombardment He has shown that the maximum quadrature squeezing of the light generated by the laser, operating far below threshold, is 50% below the vacuum-state level. The three-level atoms available in a closed cavity and pumped by coherent light generated squeezed light under certain conditions, with the maximum global quadrature squeezing is being 43% below the vacuum-state level [1] It appears to be practically more convenient to pump the atoms by coherent light than electron bombardment. We investigate the steady-state analysis of the squeezing and statistical properties of the light generated by a coherently pumped degenerate three-level laser with open cavity which is coupled to a two-mode vacuum reservoir via a single-port mirror. We carry out our calculation by putting the noise operators associated with the vacuum reservoir in normal order and by taking into consideration the interaction of the three-level atoms with the vacuum reservoir outside the cavity
