Characterization of multilayer Al doping in ZnO
Tüzemen, Ebru Şenadım; Muğlu, Günay Merhan; Alaydin, Behçet Özgür; Altun, Didem; Çetin, Selda Kılıç; Gür, Emre (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 ... -
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
Alaydin, Behçet Özgür (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
Alaydin, Behçet Özgür; Keller, Ursula; Barh, Ajanta; Gaulke, Marco; Golling, Matthias; Heidrich, Jonas (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 average output power from a backside-cooled 2-µm InGaSb VECSEL with full gain characterization
Alaydin, Behçet Özgür; Keller, Ursula; Barh, Ajanta; Gaulke, Marco; Golling, Matthias; Heidrich, Jonas (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 ... -
Watt-level and sub-100-fs self-starting mode-locked 2.4-µm Cr:ZnS oscillator enabled by GaSb-SESAMs
Alaydin, Behçet Özgür; Barh, Ajanta; Keller, Ursula; Golling, Matthias; Heidrich, Jonas; Cristopher, Phillips; Gaulke, Marco (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 ...
