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 ...
Charge-current generations and optical specifications of Gaussian quantum dot with energy-dependent potential
(2022)
We consider the energy-dependent quantum dot with GaAs/GaAlAs Gaussian potential encompassment.
Depending on the experimental or theoretical results for different types of interactions, the energy dependency can also be ...
Estimations of first 2+ energy states of even even nuclei by using artificial neural networks
(Indian Journal of Physics, 2022)
The first excited 2+ energy states of nuclei give much substantial information related to the nuclear structure. All excited states of nuclei are shown regularities in spin, parity, and energy, including these levels. In ...
Combined effects of thermodynamic factors and external fields for nonlinear optical processes of deformed Mathieu quantum dot containing central impurity
(05.08.2023)
The theoretical impact of external parameters such as the hydrostatic pressure, temperature, electric field, magnetic field, as well as the Indium (In) concentration and quantum dot width on the nonlinear optical properties ...
