The Ultimate Guide To HgGa2S4 Crystal
Blog Article
Determined by our analyze, we also suggest a whole new plan for improvement of compact high-electrical power OPO sources making use of MgO:PPLN chips of somewhat small lengths and enormous cross-sectional spot.
We report over a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) determined by the Kerr-lens-mode-locked Ti:sapphire laser given that the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP 2 , synchronously pumped inner to a MgO:PPLN femtosecond OPO, we have produced broadly tunable radiation across 5958�?117 nm making use of speedy static cavity hold off tuning, with a utmost power of sixty four μW at 6791 nm, constrained via the absorption in mirror substrates and also polarization-dependent intracavity losses.
This method will allow the operation of broadly tunable optical parametric oscillators2 (OPO) and subsequent change frequency generators3 producing tunable pulses of significant peak power. The upper Electrical power of the pump pulse trains has certain Added benefits with the operation of a synchronously pumped OPO, e.g., calm stability needs, as well as the probable to work with huge cavity losses (e.g. metal mirrors) allowing substantial tuning ranges with an individual list of mirrors and higher output-coupling factors for pulse shortening.
The significant conversion effectiveness and wide range of radiation wavelength tuning lets to count on that this product may perhaps contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the sizeable issue of huge dimension crystals growth system.
We report new experimental final results within the phase-matching Attributes of yellow shade HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-ten.5910 μm assortment. Additionally, we present new Sellmeier equations that give a excellent reproduction with the present experimental benefits together with the revealed data factors for second-harmonic era of CO2 laser radiation at nine.
PA Ref-cell, which drastically cuts down themeasurement mistakes of the methane concentration in thecase of instability
Although utilizing an institutional account for this website we don’t keep track of any own, effectiveness, practical or 1st or 3rd bash linked details.
air hole and excited in collection by a common pump beam. The stage from the interference is determined by the stage shifts at a few frequencies.
Modeling and experimental analyze on section matching of 2nd harmonic generation in various color Hg Ga 2 S four crystals are carried out. Using the known Sellmeier equations, the dispersion relation with weighting proportionally to limited-wavelength boundary of the crystal transparency band is proposed.
This paper testimonials the latest developments in crystal development and singly resonant optical parametric read more oscillators for the technology of significant solitary pulse Power and typical powers within the mid-IR from 3 to ten μm.
... The very first information around the refractive index of orange HGS posted by Levine et al. [35] included only handful of wavelengths within the noticeable and around-IR just as a demonstration of the feasibility of the crystal for birefringent section-matching. The refractive indices with the orange section ended up measured and tabulated among 0.
Quantum mechanical dependent very first theory calculations are actually used to acquire the device mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite structure for The very first time. For this, we addressed HgGa2S4 in two differing types of website symmetries in a similar space group.
One-action sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Change frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams were focused Within the crystal without the need of hurt. Mixing of cw and pulsed laser techniques was utilized to attenuate the thermal lensing consequences inside this crystal. A minimal-energy cw one.064‐μm Nd:YAG laser beam was applied because the pump, Whilst the sign beam arrived from a picosecond optical .
