We have demonstrated a loop phase-conjugate mirror that has produced up to 200 W phase-conjugate average output power at a 140% reflectivity for a CW input beam at a wavelength of 1.03 μm. A high conjugation fidelity was established by showing that

We have demonstrated stable operation of a 2-kW Yb:YAG phase-conjugate master oscillator power amplifier (PC-MOPA) laser system with a loop phase-conjugate mirror (LPCM). This is the first demonstration of a continuous wave (CW)-input LPCM MOPA opera

We describe an Er:SHARC fiber amplifier generating 1-nsec pulses having peak powers approaching 100 kW at a 30 kHz repetition rate. Pulse energies of 0.9 mJ were achieved with a longer pulse length of 15 nsec.

We have proposed, designed, manufactured and tested low loss dielectric micro-lenses for infrared (IR) radiation based on a dielectric metamaterial layer. This metamaterial layer was created by patterning a dielectric surface and etching to sub-micro

Dielectric metamaterial layers are lossless, and exhibit relatively high transmission efficiencies (contrary to plasmonic metasurfaces). Subwavelength dielectric lenses have been developed - demonstrating beam area contraction ratio of three, and ins

We modify the radiation transfer approach, accounting for refraction, and apply this model to the analysis of propagation of spatially incoherent beams in inertial nonlinear media. For double Gaussian beams, an oscillatory regime of nonlinear diffrac

A new class of optical fiber, the SHARC fiber, is analyzed in a high-power fiber amplifier geometry using the gain-filtering properties of confined-gain dopants. The high-aspect-ratio (~30:1) rectangular core allows mode-area scaling well beyond 10,0

SHARC fiber lasers offer very large rectangular core areas of 30,000 μm^2 or more, peak and average powers well beyond the state of the art, good beam quality, and a mechanical flexibility allowing compact coiling.

We demonstrated 5-mJ, 13-nsec pulses using a diode-pumped high-aspect ratio core (HARC) fiber with an active area of 30 x 580 μm2, in good agreement with our model, which predicts scalability to several 10s of mJ.

It is demonstrated that the self-starting generation for a phase-conjugate semilinear mirror is preceded by the silent zone, which is necessary for preparing a phase-conjugate generation structure in a multimode nonlinear resonator. The threshold for
