Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency era in OPGaAs
Output idler energies within the microjoule stage are received with greatest conversion efficiency of eleven% for that amplifier stage, which can be a lot more than two instances better than the effects acquired with an analogous sample with the widely spread substance AgGaS 2 .

A simple system for cutting down the loss that is due to depolarization resulting from thermally induced strain birefringence in solid-point out lasers is described. The procedure makes use of just one intracavity quarter-wave plate with its speedy or slow axis aligned parallel to the popular airplane of polarization, defined by an intracavity polarizer.
OPO have been improved by optimizing pump beam waist and OPO cavity length. Each air-spaced and strong etalons have been examined to frequency
On this Introduction We'll supply a quick overview with the significant milestones in the event of reliable-condition lasers, discuss the variety of efficiency parameters feasible with these lasers, and mention major applications.
Taxonomy, chemical bonding relations and nonlinear optical Attributes of noncentrosymmetric sulfide crystals
We present a numerical review for the design of efficient MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top-hat transverse intensity profile, in addition to a double-pass pump cavity configuration. Particularly, we examine the outcome of area condition on the conversion effectiveness. We thought of two kinds of domain structures: "ideal vertical-wall" and "wedge-shaped" domains and our numerical benefits show that at greater pump pulse energies, the conversion performance saturates, and also the saturated efficiency is almost unbiased of your area designs.
Greater-purchase nonlinear processes in substitute elements are thought of along with a discussion on materials suitability for down-conversion of close to-IR lasers to the mid-IR to meet different application demands is usually offered.
The technology of expanding mercury thiogallate crystals (HgGa2S4) is improved and significant-high-quality bulk samples are produced. The basic optical and thermal properties of those crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear qualities such as the quadratic susceptibility, tuning curves, as well as optical-harm resistance will also be established.
The electronic construction and chemical bonding in HgGa2S4 crystals developed by vapor transport method are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is uncovered being formed by splitted S 3p and Hg 6s states at binding energies BE=three seven eV plus the components at BE=seven 11 eV produced by the hybridization more info of S 3s and Ga 4s states with a powerful contribution with the Hg 5d states. At bigger binding energies the emission traces related to the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed in the photoemission spectrum.
The noticed f -to- two f frequency beats, originating straight from the OPO, may be used for self-referencing and phase locking with the pump laser comb with no need for supercontinuum technology. With a median output electricity of �?30 mW , this setup may be valuable for many different spectroscopic purposes inside the mid-IR.
Latest mid-IR NLO crystals could be divided into four classes, i.e., classical binary and ternary metallic pnictides and chalcogenides, quaternary metal chalcogenides, binary and ternary metal halides, and unique-bond-sort hybrid compounds that comprise a minimum of two different types of definitely distinctive chemical bonds within the crystal buildings. Steel pnictides and chalcogenides have got Significantly focus on growing substantial crystals. Distinct-bond-variety hybrid is a completely new family members of mid-IR NLO materials, and several of these were present in the final ten years. In metallic halide method, both equally development in rising massive crystals and exploring new types are already designed.
This can be the to start with example of a broadband OPO running across the molecular fingerprint area, and we demonstrate its likely by conducting broadband Fourier-remodel spectroscopy working with water vapor and also a polystyrene reference regular.
