Abstract
We discuss power scaling of passively modelocked lasers using multiple laser heads in the resonator We experimentally compared two different approaches for the cavity design both using three sidepumped NdYAG laser heads We obtained a recordhigh average output power of up to 27 W with close to diffractionlimited beam quality a pulse duration of 19 ps a pulse energy of 05 μJ and 23 kW peak power Singlepass secondharmonic generation in a 10mmlong LBO crystal yields 162 W of 532nm radiation
