In many scientific applications the solution of non-linear differential equations are obtained through the setup and solution of a number of successive eigenproblems. These eigenproblems can be regarded as a sequence whenever the solution of one problem fosters the initialization of the next. In addition, some eigenproblem sequences show a connection(More)
Since green laser diodes are still not commercially available, alternative technologies like frequency doubling have to be used for compact green laser sources. The goal of this work is to develop diode pumped green erbium-doped glass up-conversion waveguide lasers, instead. Planar fluoride glass waveguides are fabricated using a spin-coating technology.(More)
