Characterization of multilayer Al doping in ZnO
(24/04/2021)
ZnO, ZnO/Al, Al/ZnO/Al, and ZnO/Al/ZnO samples were deposited on c-plane sapphire and Si substrates by radio frequency magnetron sputtering (RFMS) using ZnO target. In order to form doped ZnO:Al thin films, these grown ...
Watt-level and sub-100-fs self-starting mode-locked 2.4-µm Cr:ZnS oscillator enabled by GaSb-SESAMs
(09/02/2021)
Femtosecond lasers with high peak power at wavelengths above 2 µm are of high interest for generating mid-infrared (mid-IR) broadband coherent light for spectroscopic applications. Cr2+-doped ZnS/ZnSe solid-state lasers ...
High average output power from a backside-cooled 2-µm InGaSb VECSEL with full gain characterization
(22/11/2021)
We compare the gain and continuous wave lasing properties of two InGaSb-based vertical external cavity surface emitting lasers (InGaSb VECSEL) with different heat management approaches operating at a center wavelength of ...
Effect of high bandgap AlAs quantum barrier on electronic and optical properties of In0.70Ga0.30As/Al0.60In0.40As superlattice under applied electric field for laser and detector applications
(20/01/2021)
Effect of high bandgap 0.5 nm AlAs on the electronic and optical properties of the In0.70Ga0.30As/Al0.60In0.40As superlattice is investigated by using effective mass approximation under the electric field. Electronic ...
Full optical SESAM characterization methods in the 1.9 to 3-µm wavelength regime
(01/03/2021)
Semiconductor saturable absorber mirrors (SESAMs) are widely used for modelocking of various ultrafast lasers. The growing interest for SESAM-modelocked lasers in the short-wave infrared and mid-infrared regime requires ...
High harmonic generations triggered by the intense laser field in GaAs/ AlxGa1-xAs honeycomb quantum well wires
(Elsevier, 2023)
Under constant electric and magnetic fields, the potential profile of the honeycomb quantum well wire (HQWW) is studied for varying intense laser fields to trigger and optimize high harmonics (nonlinear optical rectification, ...
High harmonic generations in GaAs/AlGaAs superlattice: Effect of electric and magnetic field
(Elsevier, 2023)
In this study, we have examined the nonlinear optical rectification (NOR), the second harmonic generation
(SHG), and the third harmonic generation (THG) coefficients of the AlxGa1-xAs/GaAs superlattice with a periodically ...
