Abstract: An optical frequency division multiplex system including a transmitter, a receiver, and a transmission path connecting the transmitter to the receiver. In the transmitter a master laser is operated to produce a central peak at an optical frequency f.sub.o with side peaks separated by an amount .DELTA.f running to both sides of the central peak. The master laser output goes through an optical isolator to an optical coupler where it is split up into N+1 beams. Each optical output from the coupler is then positioned to be coupled into N slave lasers. Each slave laser is tuned to approximately coincide with one of the side peaks thus producing a single output frequency of (f.sub.o .+-.n.DELTA.f) from each slave laser diode. Electrical modulating signals for each of N information channels are applied separately to modulate the phase of each of the slave laser outputs. The outputs of the slave lasers are then recombined in a N.times.1 optical coupler, the output of which is transmitted over a single-mode fiber linking the transmitter to the receiver. One of the outputs of the 1.times.(N+1) coupler is transmitted to the receiver over a second single-mode fiber. At the receiver, the master laser carrier is split into N spatial components by a 1.times.N coupler. These are then filtered and amplified by a second group of N slave lasers. The output from this second unmodulated group of slave lasers is combined with the combined outputs from the modulated slave lasers in an array of 2.times.1 optical couplers. Finally, the light signals emerging from the couplers are converted to electrical signals for the N information channels by an array of photodetectors.

Abstract: A system for short-range laser detection and ranging of targets can provides rapid three-dimensional, e.g., angle, angle, range, scans over a wide field-of-view. Except for the final transmit/receive lens, the disclosed LADAR system can be implemented in an all-fiber configuration. Such system is compact, low cost, robust to misalignment, and lends itself to eye-safe operation by making use of available pulsed 1550 nm fiber lasers and amplifier sources. The disclosed LADAR system incorporates many novel features that provide significant advantages compared to current LADAR systems. The disclosed system uses a monostatic fiber-based transmitter/receiver, a fiber beam scanner based on a laterally vibrating fiber, and a position sensor to monitor the transmitted beam position.

Abstract: High-resolution optical position sensing is disclosed using sparse, low-resolution detectors. Precise location of two-dimensional position or angular orientation of an optical beam at the focal plane of a sensor system is made possible using sparse low-resolution detectors. The beam may be emitted directly from a source, or scattered from a remote target. The high precision in determining the beam or focal spot location is the result of a novel data processing and analysis method for the signals from the low-resolution detectors.

Abstract: A method and device for reducing the timing jitter in a passive Q-switched Nd:YAG solid state laser by spatially selective bleaching a thin sheet of a saturable absorber of Cr+4:YAG from a direction orthogonal to the direction of laser emission where the Cr+4:YAG transmission increases 18% when the bleaching probe beam is a single laser diode bar. For steady state operation of a passive Q-switched laser, the pulse-to-pulse timing jitter showed a −12× reduction in standard deviation from 241 nsec for free running operation to 20 nsec with optical triggering.

Abstract: A compact monostatic optical transmitter/receiver device simultaneously transmits an optical beam and collects returning light using a single lens or optical aperture. The system provides automatic alignment of the transmit and receive aperture and is compatible with fiber-coupled laser sources. Transmit light is emitted from a double-cladding fiber core while received light is coupled into the inner cladding of the same fiber. The transmit light propagating in the core and the received light propagating in the inner cladding are separated by the means of a diplexer comprised of a fused fiber coupler or a fiber-coupled micro-optic device.
