Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency era in OPGaAs
Effects of thermal conductivity measurements are described for a number of of the more lately made nonlinear optical crystals. New or considerably revised values of thermal conductivity were being acquired in 6 elements. Notable thermal conductivities measured were being Individuals for AgGaS2 [0.014 W/(cm K) and 0.
crystals with ultrafast Yb-ion laser pump is proposed. The results type a beneficial reference for the selection of resources
By employing intracavity dispersion Management, close to-remodel-minimal signal pulses of �?a hundred fs period with smooth single-peak spectrum are attained at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the most beneficial of our expertise, This really is The 1st time this sort of simple idler powers inside the deep-IR are generated from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition charge.
Self-referenced octave-extensive subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
brought about oscillations from the idler wavelength of lower than 200MHz around 300s; the short-term stability was a lot less than 3MHz
The generation of tunable pico- and femtosecond light pulses with parametric frequency conversion processes has attracted improved consideration recently1. New crystal elements, as BBO, LBO, and KTP, with remarkable nonlinearity and high harm threshold are now accessible, and pump lasers of improved balance allow the reliable Procedure of optical parametric oscillators. Parametric products pumped ... [Demonstrate complete summary] either by cw modelocked lasers or by single intensive ultrashort pulses are already created. During this contribution parametric devices are reviewed which might be pumped by extreme pulse trains of a few microseconds duration and repetition charges as many as 50Hz.
We existing a numerical research for the look of productive MgO:PPLN centered pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of leading-hat transverse intensity profile, as well as a double-move pump cavity configuration. Especially, we examine the impact of area shape to the conversion performance. We regarded as two sorts of area constructions: "fantastic vertical-wall" and "wedge-formed" domains and our numerical results demonstrate that at greater pump pulse energies, the conversion effectiveness saturates, as well as the saturated efficiency is nearly impartial in the area designs.
The precise heat and thermal conductivity of HgGa2S4 are calculated. It can be concluded that the mixed Attributes of HgGa2S4 crystals can offer for them a number one posture One of the elements Utilized in nonlinear-optical equipment for mid-IR-frequency conversion.
The 3rd harmonic of CO2-laser radiation has actually been acquired by passing the laser beam via two CdGeAs2 crystals in tandem, with the 1st crystal oriented for second-harmonic era and the 2nd for sum mixing. Applying This system, We've achieved an average external conversion performance of one.
The electronic structure and chemical bonding in HgGa2S4 crystals developed by vapor transport system are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is discovered to become fashioned by splitted S 3p and Hg 6s states at binding energies BE=three 7 eV and the parts at BE=7 11 eV created with the hybridization of S 3s and Ga 4s states with a powerful contribution through the Hg 5d states. At better binding energies the emission lines associated with the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed during the photoemission spectrum.
with the detection of molecular trace gasses. The oscillation threshold, output energy and balance of The one resonant
A straightforward quantum product agrees very well With all the experimental effects and causes it to be feasible to interpret the result when it comes to
Distinction frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams were concentrated Within the crystal with no destruction. Mixing of cw and pulsed laser units was used to attenuate the thermal lensing effects within this crystal. A very low-ability cw one.064‐μm Nd:YAG laser beam was utilised as being the pump, While the signal read more beam came from the picosecond optical .
