摘要： A laser apparatus (10) has a coherent master oscillator radiation source (30) for driving a plurality of laser gain elements (20) positioned in a operationally parallel configuration so as to receive unamplified radiation (40) from master oscillator (30) and transmitting amplified radiation (44). Input means (60) couples portion of radiation (40) from master oscillator to each of said gain elements (20). Phase conjugate reflector means (80) operatively coupled to gain elements (20) reflects the phase conjugate of amplified radiation (44) back into the gain elements (20) where it is further amplified. Output coupling means (90) couples amplified radiation from the plurality of gain elements (20) out of the laser apparatus as a single coherent output beam of radiation.

摘要： Apparatus for providing an amplified, phase-conjugated output beam. A nonlinear medium, gain medium, and output device are disposed along an optical path to form a ring resonator. An external laser source provides laser light to one end of the nonlinear medium which induces stimulated Brillouin scattering in the medium. Light provided by the gain medium at a first predetermined frequency is reflected from the acoustic waves traversing the nonlinear medium at a second predetermined frequency. The reflected light traverses the optical path through the gain medium and impinges upon the other end of the nonlinear medium, where it is further reflected from the acoustic waves. This reflected light is frequency shifted to the original predetermined frequency. A portion of the light at the predetermined frequency is coupled out of the resonator as an amplified phase-conjugated output beam by means of the output device. Alternatively, output beams at both the first and second predetermined frequencies may be provided.

摘要： Laser apparatus is disclosed which employs the principles of phase conjugation to provide for short-pulse operation. A phase-conjugate reflector, lasing medium, and output coupling device are arranged to form a laser resonator. The lasing medium may be pumped by a conventional pump source to produce population inversion in the lasing medium. The phase-conjugate reflector is pulsed by means of a pulsed pump source which applies a periodic train of short laser pulses having high peak power and low average power thereto. The short-duration pulses create high reflective efficiencies in the phase-conjugate reflector, while minimizing the overall energy demands on the system. Additionally, the pump source which pumps the lasing medium may also provide pulsed energy thereto which is synchronous with the pulsed energy provided by the pulsed pump source to the phase-conjugate reflector. Accordingly, the system provides for a series of short pulsewidth laser pulses at its output.
