Signal amplification and control in optical cavities with off-axis feedback.
We consider a large class of optical cavities and gain media with an off-axis external feedback which introduces a two-point nonlocality. This nonlocality moves the lasing threshold and opens large windows of control parameters where weak light spots can be strongly amplified while the background radiation remains very low. Furthermore, transverse phase and group velocities of a signal can be i...
متن کاملParametric image amplification in optical cavities
We show the possibility of noiseless amplification of an optical image in cavities containing a parametric oscillator. We consider a confocal ring cavity with plane mirrors and compare with the case of planar cavity. In the latter case the system operates with severe spatial limitations, while in the confocal case, there is the possibility of preserving the signal-to-noise ratio while amplifyin...

Brillouin signal amplification in pumped erbium-doped optical fiber
Amplification of Brillouin scattering signal extends the measurement range and improves the signal-to-noise ratio of fiber-optic distributed Brillouin sensors. Here, we investigate the amplification effect of a 980-nm pump laser on Brillouin gain spectrum in an erbium-doped optical fiber. The Brillouin-scattered Stokes power increased exponentially with increasing pump power, exhibiting approxi...
متن کاملUltrasensitive absorption spectroscopy with a high-finesse optical cavity and off-axis alignment.
A simple and easy to use method that allows high-finesse optical cavities to be used as absorption cells for spectroscopic purposes is presented. This method introduces a single-mode continuous-wave laser into the cavity by use of an off-axis cavity alignment geometry to eliminate systematically the resonances commonly associated with optical cavities, while preserving the absorption signal amp...
