Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency era in OPGaAs
Outcomes of thermal conductivity measurements are claimed for several of the greater lately formulated nonlinear optical crystals. New or significantly revised values of thermal conductivity ended up attained in six resources. Notable thermal conductivities measured were These for AgGaS2 [0.014 W/(cm K) and 0.

The large conversion efficiency and wide range of radiation wavelength tuning lets to be expecting this materials may possibly contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the significant problem of huge size crystals growth method.
Self-referenced octave-vast subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
caused oscillations inside the idler wavelength of under 200MHz about 300s; the quick-expression balance was below 3MHz
The era of tunable pico- and femtosecond gentle pulses with parametric frequency conversion procedures has captivated greater notice recently1. New crystal elements, as BBO, LBO, and KTP, with top-quality nonlinearity and high damage threshold are now readily available, and pump lasers of enhanced balance allow the trustworthy Procedure of optical parametric oscillators. Parametric equipment pumped ... [Exhibit full summary] both by cw modelocked lasers or by single powerful ultrashort pulses happen to be formulated. During this contribution parametric programs are mentioned that are pumped by intense pulse trains of some microseconds duration and repetition charges as much as 50Hz.
We current a numerical study for the look of efficient MgO:PPLN dependent pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top rated-hat transverse depth profile, and also a double-move pump cavity configuration. In particular, we investigate the result of domain form within the conversion performance. We regarded two types of area structures: "ideal vertical-wall" and "wedge-formed" domains and our numerical effects display that at greater pump pulse energies, the conversion performance saturates, as well as saturated performance is almost independent on the area designs.
Modeling and experimental analyze on stage here matching of second harmonic technology in various colour Hg Ga two S four crystals are carried out. Using the identified Sellmeier equations, the dispersion relation with weighting proportionally to quick-wavelength boundary on the crystal transparency band is proposed.

The Digital composition and chemical bonding in HgGa2S4 crystals developed by vapor transportation method are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is discovered to become formed by splitted S 3p and Hg 6s states at binding energies BE=3 7 eV as well as the elements at BE=7 11 eV generated through the hybridization of S 3s and Ga 4s states with a powerful contribution through the Hg 5d states. At increased binding energies the emission traces connected with the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed while in the photoemission spectrum.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser system. By making use of a three hundred μm long magnesium-doped periodically poled LiNbO 3 crystal since the parametric get medium and configuring the OPO to be a chirped-pulse oscillator, we obtained mid-infrared emission getting an instantaneous bandwidth covering 3084�?466 nm. This outcome represents, to the top of our know-how, the widest instantaneous bandwidth attained from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the huge potential of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-fast OPOs.
