.. [Show comprehensive abstract] parametric oscillator. The two independently targeted beams ended up created to overlap In the crystal. The concentrating parameters of The 2 beams were being in regards to the similar. The focusing purpose designed by Boyd and Kleinman for tightly concentrated beams was extended to periodically poled crystals so as to fit the temperature-tuning curve. A 0.66%/W efficiency was acquired for the real difference frequency mixing process.
Output idler energies to the microjoule degree are obtained with highest conversion efficiency of 11% for the amplifier phase, which happens to be in excess of two moments better than the outcomes obtained using an analogous sample in the broadly unfold materials AgGaS 2 .
Moreover the compactness and benign running options, it absolutely was the enormous adaptability in style and design and output features that led into the achievements of good-point out lasers over the past 40 several years.
By employing intracavity dispersion Regulate, around-rework-constrained signal pulses of �?100 fs length with clean solitary-peak spectrum are achieved at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the best of our awareness, This is certainly the first time such sensible idler powers from the deep-IR happen to be created from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition charge.
We report new experimental results about the section-matching Attributes of yellow colour HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm range. Additionally, we present new Sellmeier equations that offer a excellent replica in the current experimental final results together with the released facts points for next-harmonic technology of CO2 laser radiation at 9.
induced oscillations from the idler wavelength of a lot less than 200MHz more than 300s; the small-time period steadiness was fewer than 3MHz
Optical Homes of orange phased HgGa2S4 crystal is investigated. Technology of tunable Center infrared radiation by second harmonic of tunable CO2 laser radiation has been demonstrated. Second harmonic conversion efficiency with respect to other infrared crystal has also been mentioned.
air hole and enthusiastic in collection by a standard pump beam. The period on the interference will depend on the period shifts at three frequencies.
Reliable state polymerization of diacetylenes The crystal read more composition of HAlSi2O6 using a keatite-type framework Syntheses and crystal buildings of α
stabilize and tune the OPO, from which the sound etalon gave a greater efficiency. Temperature oscillations while in the PPLN crystal
The electronic construction and chemical bonding in HgGa2S4 crystals developed by vapor transportation strategy are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is discovered to be formed by splitted S 3p and Hg 6s states at binding energies BE=three seven eV as well as the parts at BE=seven eleven eV created from the hybridization of S 3s and Ga 4s states with a powerful contribution in the Hg 5d states. At greater binding energies the emission lines linked to the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed within the photoemission spectrum.
for that detection of molecular trace gasses. The oscillation threshold, output electric power and stability of The one resonant
The selected nonlinear crystals exhibit greater nonlinear conversion efficiency as compared to AgGaS two , with BaGa 2 GeS six additionally presenting a narrower angular spectrum of spontaneous parametric down conversion, advantageous in interferometric schemes. Our findings set up a pathway for integrating State-of-the-art crystal systems into mid-infrared metrology and imaging programs, environment the phase for long term developments in nonlinear interferometry and spectroscopy.
3% rms about twelve h in good beam excellent. The near-IR signal pulses within the OPO Use a Gaussian pulse duration of �?19 ps , measured at 1284 nm. We now have investigated the temperature tuning traits in the OPO and in comparison the info With all the theoretical calculations using the most recent Sellmeier equations and thermo-optic coefficients for your crystal. To the most beneficial of our knowledge, this is the very first picosecond OPO based on CSP running at MHz repetition premiums.
