Abstract :
Summary form only given. For selective photocoagulation in ophthalmology /spl mu/s-laser pulse durations with pulse energies of some millijoules at a repetition rate of 500 Hz in the green spectral range are required. A suitable solid state laser medium to achieve Q-switched pulse durations of some hundred /spl mu/s is Nd:LiYF/sub 4/ due to its low stimulated emission cross section. In order to further extend the pulse duration highly efficient intracavity SHG is applied.
