and working conditions for the practical design and style of higher ability femtosecond optical parametric oscillators with excitation
Output idler energies on the microjoule amount are attained with most conversion performance of 11% with the amplifier phase, that's a lot more than two periods a lot better than the outcome received with the analogous sample with the widely distribute content AgGaS two .
This method will allow the operation of widely tunable optical parametric oscillators2 (OPO) and subsequent big difference frequency generators3 creating tunable pulses of significant peak electricity. The higher Power from the pump pulse trains has particular Rewards for the operation of the synchronously pumped OPO, e.g., relaxed stability specifications, and also the probable to work with large cavity losses (e.g. steel mirrors) permitting huge tuning ranges with one set of mirrors and large output-coupling variables for pulse shortening.
In both of those the instances received device mobile parameters are very same, which shows the accuracy of current strategy. The electronic band constructions show the semiconducting behavior in equally the instances. The density of states plot are studied and talked about.
in the laser emission wavelength. The minimum calculated background sign on the PA sensor (employing large purity
brought about oscillations inside the idler wavelength of under 200MHz around 300s; the small-phrase security was a lot less than 3MHz
Taxonomy, chemical bonding relations and nonlinear optical Homes of noncentrosymmetric sulfide crystals
A technique is made to unravel the procedure of shortened equations describing parametric era inside of a one-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals plus the ideal reflection coefficient from the output mirror are believed as opposed to the pump Vitality density Wp at different values of your OPO nonstationarity .

The technological innovation of escalating mercury thiogallate crystals (HgGa2S4) is improved and substantial-high quality bulk samples are created. The fundamental optical and thermal Homes of check here those crystals are studied. The transmission spectra of mercury thiogallate are measured and its nonlinear characteristics including the quadratic susceptibility, tuning curves, as well as optical-destruction resistance also are decided.
... The 1st details to the refractive index of orange HGS revealed by Levine et al. [35] bundled only couple wavelengths within the visible and in the vicinity of-IR equally as an illustration of the feasibility of this crystal for birefringent phase-matching. The refractive indices with the orange section have been calculated and tabulated between 0.
Observe: Writer names are going to be searched during the keywords area, also, but that could discover papers in which the individual is talked about, as an alternative to papers they authored.
New mid-IR NLO crystals may be divided into four classes, i.e., classical binary and ternary metallic pnictides and chalcogenides, quaternary metallic chalcogenides, binary and ternary steel halides, and unique-bond-style hybrid compounds that comprise at least two kinds of obviously unique chemical bonds during the crystal constructions. Metal pnictides and chalcogenides have acquired much focus on growing substantial crystals. Distinct-bond-type hybrid is a fresh family members of mid-IR NLO supplies, and lots of of these have been found in the last decade. In metallic halide process, equally development in developing massive crystals and identifying new types are already built.
three% rms above 12 h in fantastic beam good quality. The close to-IR signal pulses from the OPO Use a Gaussian pulse duration of �?19 ps , measured at 1284 nm. We've got investigated the temperature tuning properties of your OPO and when compared the info Along with the theoretical calculations utilizing The latest Sellmeier equations and thermo-optic coefficients with the crystal. To the top of our knowledge, This is actually the to start with picosecond OPO depending on CSP running at MHz repetition premiums.
