Photorefractive holography has an advantage over digital holography by adaptively rejecting non-image-bearing multiple scattering. High-speed photorefractive quantum wells allow scrambling of spatial coherence of the illumination, reducing channel cross-talk. View full abstract»

Photorefractive properties of lithium niobate and tantalate are studied in infrared using whispering gallery mode resonators. Unusual dynamics in the resonator spectra with applied light is observed. View full abstract»

We report on direct experimental evidence that light-induced ionic displacement, driven by charge separation, is responsible for the enormous enhancement of the nonlinear properties of CdZnTe:V crystals. View full abstract»

We demonstrate self-pumped optical phase conjugation in Te-doped Sn₂P₂S₆ up to a wavelength of 1.06 mum. A phase conjugate reflectivity of more than 40 percent with a very fast rise time below 100 ms has been measured. View full abstract»

We report holographic recording of second harmonic radiations emitted from nanocrystals under femtosecond laser excitation. Our results show great promise of this novel technique to provide four-dimensional images for highly dynamic micro- and nano-systems. View full abstract»

Double-functional dynamic holographic interferometer was realized on CdTe: V crystals using 100 mW IR CW laser (1064 nm). Both electrical (holographic electro-motive force, V=2.4 mV) and optical signals (beam coupling) are detected directly by oscilloscope without amplifiers. View full abstract»

Thermal gratings are recorded in silver nanoparticle suspensions by nanosecond pulsed holography. Initial transients in diffraction efficiency demonstrate competing effects in grating formation. The gratingpsilas final decay is consistent with the suspensionpsilas thermal conductivity. View full abstract»

19 mW of continuous-wave ultraviolet radiation at 320 nm with ~9% optical-to-optical efficiency is demonstrated by intracavity frequency-doubling of a Pr:LiYF₄ laser, excited by an optically pumped semiconductor laser. View full abstract»

High-efficiency high-power operation of 2 at.% crystalline Nd:YAG is demonstrated. CW output power of 46.1 W and slope efficiency of 60% are obtained, and 11 mJ pulses at 100 Hz with QCW-pumping are achieved with 12 ns Q-switched pulses. View full abstract»

Q-switching of a high average power Nd:YAG planar waveguide laser with an unstable resonator is achieved using an acousto-optic modulator. Analysis of the resonator dynamics is carried out using a multi-phase screen modulator model. View full abstract»

A novel resonator concept that produces axisymmetric output from a thin-planar gain medium with a highly elliptical pump cross-section is described. Preliminary studies of this power-scalable approach using a Nd:YLF slab laser are presented. View full abstract»

A pair of nearly identical volumetric Bragg gratings held at different temperatures serving as the end mirrors of a Ti:sapphire laser made possible very narrow output linewidth and enabled easy optimization of the laser output. View full abstract»

Optical silicon carbide is proposed for face cooling in bulk solid-state lasers instead of currently used diamond. First demonstrations resulted in 24% slope efficiency of the SiC-cooled Nd:YAG laser despite double SiC/YAG interface intracavity loss. View full abstract»

We present high power amplified spontaneous emission sources with spatial selectivity, based on an ultra-high gain diode-pumped Nd:YVO₄ crystal in a bounce amplifier geometry. Output power 30 W was achieved with near diffraction-limited spatial quality. View full abstract»

We demonstrate a tunable optical filter with extinction ratio of 37 dB by integrating microring resonator with a microfluidic chip. Tuning is obtained by on-chip mixing of two liquids with different refractive indices. View full abstract»

We show experimentally an all-optical analogue to electromagnetically induced transparency due to coherent interference between two coupled resonators. We measured an EIT-like resonance mode with quality factor of 11,800 using silicon ring resonators. View full abstract»

System functionalities of matched filtering, channel banding, and wavelength demultiplexing are demonstrated using a unique MEMS-actuated microdisk resonator filter with dynamically tunable bandwidth. Error free operation of demultiplexed channel is realized. View full abstract»
