two–10.8-µm wavelength region. A further crucial limitation with the pump ability related which has a thermal lensing outcome in crystal was determined experimentally. A comparison was made of AgGaSe2 and ZnGeP2 crystals as elements well suited for the productive technology of the next harmonic of cw CO2 laser radiation.

We make substantial-order harmonics from crystalline solids utilizing a tunable mid-IR OPA with 50 kHz repetition fee. Applying nonlinear self-compression in YAG crystals, we make sub a few-cycle pulses at 3.8 μm wavelength for high harmonic spectroscopy. Examine much more
The dislocations are traced via the repetition of etching from epitaxial layer towards the interface. The results show that dislocations from the substrates are predicted to bend together the route normal to the epitaxial development direction within the interface.
Be aware: Author names might be searched during the key phrases field, also, but that may uncover papers in which the individual is mentioned, rather then papers they authored.
Because of the great comprehensive functionality plus the crucial application benefit in laser industry, they've got captivated A great deal consideration at your house and overseas. The development of crystal growth and laser output of BGSe and BGGSe are summarized, and the future improvement is prospected.

Be part of ResearchGate to find out and not sleep-to-day with the newest study from primary authorities in CO2 Laser and a number of other scientific matters.
24% which can be similar with a person attained with high repetition amount reduced-energy laser devices like in [9]. Taking into consideration a probability to improve pump pulse Vitality of our setup approximately ~ten mJ, the DFG pulse Power is often elevated approximately ~24 μJ at a similar efficiency, on the other hand, it needed a large-aperture, ~15 mm in diameter BGGSe sample. Common DFG pulse Power in AGS was not confidently measured with Ophir-3A electricity meter due to its small signal.
The actions of dislocations inside the interfacial location involving the epitaxial layer grown with the liquid stage plus the substrate of GaAs is investigated. Observations of dislocations lying along the 〈110�?directions were completed making use of an optical microscope soon after shallow etching using a new chemical etchant.
A not-for-gain organization, IEEE is the planet's biggest specialized Qualified Business committed to advancing technological know-how for the good thing about humanity.
It is proven there are wavelength combos at which the successful nonlinearity coefficient varies only a bit in a wide frequency band.
The nature of the instability and DFG energy lessen will not be very clear for click here us. One of the reasons could be linked which has a nonlinear absorption and plasma development, respectively, that causes reflection/scattering/absorption of your longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Power is presented in Fig.
