US Classification:

330 43

Abstract:

A four-pass conjugate optical amplifier system and method are disclosed in which a linear polarized optical beam is directed by various optical elements through four passes of a power amplifier, preferably a diode laser structure. The beam is phase conjugated at the optical midpoint between the second and third amplifying passes, and is controlled by the optical elements so that its polarization is substantially the same during the first and second passes, and again substantially the same during the third and fourth amplifying passes. This is accomplished by a reflective coating on the back facet of the diode laser structure, with a non-reciprocal polarization rotation element located in the beam path between the phase conjugate mirror and power amplifier. For considerably enhanced power amplification, the beam may be divided into an array of subbeams, which are individually amplified by four passes through respective power amplifiers. The subbeams are processed by the optical system so that they recombine into a single coherent output beam after full amplification.

Abstract:

A phase conjugate resonator (PCR) employing at least one phase conjugate mirror (PCM) provides high resolution spatial detection of individual locations in a two-dimensional optical array which exceed or fall below a threshold level. In one embodiment the optical intensity profile under investigation is imposed either onto one or both of the pump beams of a degenerate four-wave mixing PCM. In another embodiment a pair of PCMs are used as the two mirrors forming the PCR, with the pump beams for one PCM modulated and the pump beams for the other PCM serving as a threshold reference. In either case, the spatially modulated optical output may be read out with multiple detectors or an imaging system, or the cumulative area output of the PCR can be read out with a single detector to characterize the intensity profile relative to the threshold.
