735-nm tapered diode lasers with nearly diffraction-limited beam properties at P = 2 W

Summary from only given. Tapered diode lasers optimized for /spl lambda/ = 735 nm will be presented. For the tapered lasers tensile-strained GaAsP quantum wells embedded in AlGaAs were applied which ensures high reliability. Examples for applications are photodynamic therapy (PDT) and pumping of solid-state lasers.
