We crank out higher-purchase harmonics from crystalline solids employing a tunable mid-IR OPA with fifty kHz repetition price. Employing nonlinear self-compression in YAG crystals, we deliver sub three-cycle pulses at 3.8 μm wavelength for prime harmonic spectroscopy. Examine extra
The dislocations are traced with the repetition of etching from epitaxial layer on the interface. The effects exhibit that dislocations within the substrates are expected to bend together the path typical to your epitaxial expansion route with the interface.
Take note: Author names will be searched while in the key terms area, also, but which could come across papers where the person is talked about, rather than papers they authored.
Though employing an institutional account for this Internet site we don’t monitor any own, efficiency, purposeful or 1st or third get together connected information.
In the final a long time, mid-infrared (three–twelve μm) laser resources utilizing crystals with nonlinear optical Qualities have attracted a certain awareness due to their prospective apps in various fields like optical counter-measures and remote chemical sensing. As transparency of widespread oxide crystals is restricted to about four μm, lots of researches happen to be focused on chalcopyrite compounds because of their wide transparency within the mid-IR assortment and their sturdy nonlinear optical coefficients. You will find a have to have of these types of crystals equipped to transform competently the in the vicinity of infrared wavelengths from commercially available lasers into wavelengths higher than five μm through Optical Parametric Oscillators (OPO) devices.
Topics is usually refined even further while in the search results. The subject aspect will reveal the high-amount subjects related to the articles returned during the search engine results. Unique COLLECTIONS
Exclusive emphasis is BaGa2GeSe6 Crystal going to be offered to The existing specialized limitations and availability of pump laser features and nonlinear crystal Qualities. Browse far more
The habits of dislocations from the interfacial area in between the epitaxial layer grown within the liquid stage and the substrate of GaAs is investigated. Observations of dislocations lying together the 〈a hundred and ten�?Instructions were performed working with an optical microscope soon after shallow etching that has a new chemical etchant.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is usually a recently formulated nonlinear product that is certainly attractive for ultrabroad frequency mixing and ultrashort pulse era due to its comparably very low dispersion and large problems threshold. A numerical study demonstrates the fabric’s capability for octave-spanning mid-infrared pulse generation approximately eighteen µm. In a first experiment, we display that a protracted crystal duration of 2.
