In this paper, a coherent lightwave transmitter includes a relatively low power, single frequency laser which provides an injection locking signal to a plurality of higher power lasers located in separate, parallel optical paths.Abstract:
A coherent lightwave transmitter includes a relatively low power, single frequency laser which provides an injection locking signal to a plurality of higher power lasers located in separate, parallel optical paths. A modulator is interposed between the single frequency laser and the higher power lasers, and the outputs of the latter are added constructively to form a high power transmitter output. Feedback control of the optical path lengths to maintain constructive interference is also described.read more

Modulated high-power optical source
TL;DR: An apparatus for generating relatively high-power, modulated optical beams is described in this article, which comprises a first element for emitting a relatively low-power laser beam at a preselected wavelength, means for focusing the laser beam into a focused beam, a damage-resistant integrated optic modulator responsive to the focused beam for developing a modulated beam, optical means for shaping the modulated beacons into a shaped modulated beacon, and semiconductor means having a large active area responsive to shape modulated beams.

Optical transmitter of modulated signals
TL;DR: In this paper, a split waveguide is used as the frequency shifter and modulator in a three-frequency heterodyne system, where the orthogonal signals are obtained by separating the signals in frequency or by quadrature encoding.
Patent
Optical transmission system
TL;DR: In this article, a single optical transmitter which can be an optical modulator such as a lithium niolate switch is used to impress a digital signal on a CW optical beam to obtain two digital optical outputs.

Hydraulic optimization of drilling fluids in borehole drilling
TL;DR: In this paper, a method for optimizing drilling fluid hydraulics when drilling a well bore is disclosed, where the drilling fluid is supplied by a surface pump through a drill string to a drill bit, and the flow through the devices is adjusted, thereby setting the pressure drop and the fluid flow rate through each device.

Injection locking of argon-ion lasers

TL;DR: Using an injection-locking technique, high-power single-frequency emission from a multimode argon-ion laser is obtained and a phase-control loop permits the stable, coherent summation of the beams from the two lasers.

Phase locking of lasers by an injected signal.
TL;DR: An analysis is presented to determine if the effects of mirror fluctuations that are due to mechanical vibrations tend to randomize the phases between lasers in the array by injection locking.
