OBJECTIVE The aim of this study was to evaluate clinical efficacy of InGaAsP diode laser as adjunct to traditional scaling and root planing. BACKGROUND DATA The use of laser is one of the most recent methods in nonsurgical periodontal treatment. Efficacy and side effects of each type of laser treatment have yet to be determined. METHODS Thirty patients suffering from moderate periodontal di...
LAser Detection And Ranging (LADAR) is a promising tool for precise 3D-imaging, which enables field surveillance and target identification under low-light-level conditions in many military applications. For the time resolution and sensitivity requirements of LADAR applications, InGaAsP/InP Geiger-mode (GM) avalanche photodiodes (APDs) excel in the spectrum band between 1.0~1.6 μm. Previously MI...
The importance of the electron loss from the separate confinement layer (SCL) to the p-cladding in 1.5 μm lasers is analysed comparing two structures. One is a regular structure with strained InGaAsP quantum wells and a 1.15 μm emitting InGaAsP SCL and the second one incorporates an additional In0.81Ga0.19P electron stopper layer (about 50 meV high) at the interface between the p-cladding and t...
