Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency generation in OPGaAs
We report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-mode-locked Ti:sapphire laser since the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP 2 , synchronously pumped inner to some MgO:PPLN femtosecond OPO, We've got created broadly tunable radiation throughout 5958�?117 nm utilizing fast static cavity delay tuning, using a greatest ability of sixty four μW at 6791 nm, confined by the absorption in mirror substrates in addition to polarization-dependent intracavity losses.
Other than the compactness and benign operating features, it had been the large versatility in style and design and output characteristics that led for the good results of reliable-point out lasers throughout the last forty many years.
Experiments of viable pump laser technologies suited to ultrafast femtosecond OPOs according to CdSiP 2 are reviewed, plus the favorable linear and nonlinear optical Attributes, as well as distinctive stage-matching qualities of CdSiP 2 , are offered applying The newest Sellmeier equations for the fabric. The explained experimental results characterize the very best output pulse Vitality and file ordinary energy while in the ultrafast picosecond and femtosecond time scales across the 6–7 μm spectral array thus far.
Self-referenced octave-broad subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
The calculated core degree binding energies are in contrast with People of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being unbiased around the technological situations of crystal progress. In distinction to your valence band spectrum, the distribution of electron states in the bandgap of HgGa2S4 crystals is observed to become strongly dependent upon the technological situations of crystal development as demonstrated with the photoluminescence Investigation.
Optical Homes of orange phased HgGa2S4 crystal is investigated. Era of tunable Center infrared radiation by second harmonic of tunable CO2 laser radiation has long been demonstrated. 2nd harmonic conversion efficiency with regard to other infrared crystal has also been talked about.
This new edition continues to be updated and revised to includeimportant developments, principles and systems that haveemerged Considering that the publication of the very first edition.
The precise heat and thermal conductivity of HgGa2S4 are measured. It can be concluded which the merged Houses of HgGa2S4 crystals can provide for them a leading position among the products Employed in nonlinear-optical products for mid-IR-frequency conversion.
This paper opinions the new developments in crystal advancement and singly resonant optical parametric oscillators for that era of substantial solitary pulse Vitality and typical powers in the mid-IR from 3 to 10 μm.
The electronic structure and chemical bonding in HgGa2S4 crystals grown by vapor transport technique are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is identified to get fashioned by splitted S 3p and Hg 6s states at binding energies BE=3 7 eV as well as the parts at BE=seven eleven eV produced because of the hybridization of S 3s and Ga 4s states with a solid contribution within the Hg 5d states. At higher binding energies the emission strains related 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.
Quantum mechanical dependent very first principle calculations have been used to get the unit mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for The very first time. For this, we handled HgGa2S4 in two differing kinds of web-site symmetries in the exact same Area team.
Solitary-stage sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
three% rms more than twelve h in very good beam good quality. The around-IR signal pulses with the OPO Have a very Gaussian pulse length of �?19 ps , measured at 1284 nm. We have now investigated the temperature read more tuning qualities with the OPO and in contrast the data Along with the theoretical calculations utilizing The latest Sellmeier equations and thermo-optic coefficients for the crystal. To the top of our awareness, This is actually the initially picosecond OPO according to CSP working at MHz repetition premiums.
