چکیده
Experimental results with second-harmonic 460 nm-wavelength emission are presented. A profound analytical description of the intra-cavity beam shaping properties of the resonator based on the ABCD-law provides an effective design tool for the construction of appropriate resonator setups. Also described is the layer design of the optically pumped laser chip in which the fundamental radiation is generated. Overall conversion efficiencies up to 14.5% and a maximum power of 1.6W are demonstrated.

Optically pumped semiconductor disk lasers (OPSDLs) with extended cavities are surfaceemitting laser devices which efficiently convert the low-beam-quality emission of a pump laser to a high-beam-quality circular non-astigmatic laser emission. Furthermore, the extended cavity can be utilized for intra-cavity second harmonic generation by insertion of nonlinear optical crystals. By that way, the...
