Paper Abstract
VECSELs are excellent high power semiconductor lasers with diffraction-limited circular output beam and outstanding
modelocking performance. The output power can be scaled up by simply increasing the mode area on the gain region.
Electrical pumping requires doped layers and also requires changes in the epitaxial design. Crucial for high power
operation is a low electrical resistance, because electrical power heats the device. The p-doped mirror gives the largest
contribution to the electrical resistance. There are certain possibilities to reduce the resistance while keeping the optical
losses as low as possible. Among these techniques are graded interfaces and improved doping schemes.
