Pulsed Squeezed Light
Generation of squeezed light is at present limited to narrow regions of the optical spectrum.(1–3) For the parametric amplifiers used to generate squeezed light, this limit is imposed by the following properties of the nonlinear material used for the parametric process: 1) small nonlinear response, 2) linear losses, 3) insufficient laser pump power and 4) optical damage at high pump powers. Optical cavities have been used(1,2) to enhance the nonlinear interaction for continuous wave CW pumping but this limits the bandwidth and also increases the total linear loss.
