We make large-buy harmonics from crystalline solids employing a tunable mid-IR OPA with fifty kHz repetition fee. Working with nonlinear self-compression in YAG crystals, we produce sub three-cycle pulses at three.eight μm wavelength for high harmonic spectroscopy. Read through far more

Which crystal type of ZrO//two is cryStallized from Zr(OH)//4 trusted the h2o vapor pressures from the crystallization stage. The contents of monoclinic crystals greater While using the drinking water vapor pressures. Read through far more
Because of the exceptional complete general performance as well as the essential application price in laser industry, they may have attracted Significantly awareness in your house and overseas. The progress of crystal progress and laser output of BGSe and BGGSe are summarized, and the future progress is prospected.

Laser-induced destruction threshold from the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm inside the nanosecond routine
24% which can be comparable with a single obtained with significant repetition charge lower-Strength laser methods like in [nine]. Bearing in mind a possibility to raise pump pulse Power of our setup around ~10 mJ, the DFG pulse Power might be improved around ~24 μJ at the same performance, however, it required a large-aperture, ~15 mm in diameter BGGSe sample. Ordinary DFG pulse Vitality in AGS was not confidently measured with Ophir-3A energy meter as a result of its reduced sign.
The habits of dislocations from the interfacial region between the epitaxial layer grown click here from the liquid section as well as substrate of GaAs is investigated. Observations of dislocations lying together the 〈a hundred and ten�?Instructions had been performed employing an optical microscope immediately after shallow etching by using a new chemical etchant.
A not-for-gain Firm, IEEE is the world's biggest technical Skilled Firm committed to advancing technology for the good thing about humanity.
The pump pulse Electrical power was managed by a variable diffraction attenuator. Its polarization was tuned by ninety° with a 50 percent-wave plate since it needed to be regular wave from the BGGSe (when AGS crystal was utilised, the signal beam polarization was tuned). The sign beam was targeted by spherical mirror (M2, the focal duration of 2 m) into a gasoline tube of one.
BaGa2GeSe6 crystals are utilized for nonlinear optical frequency conversion in their transparency vary. The wavelengths at which highest conversion efficiencies may be obtained as well as tuning selection for change-frequency era are found.
