Development of a High Performance Green Laser Cavity for Retinal Photocoagulation,etic retinopathy, retinal detachment, retinal tears, retinal hemorrhage, vein occlusion and Glaucoma. The cavity was designed in a “V” folded shape side pumped. The maximum power output reached for this cavity architecture was 4.0W for 2.0 seconds pulse duration and 3.0W for 4.0 seconds pulse duration, both cases with duty-cycle up to 50%.
