The resonator stability conditions were analyzed graphically for various resonator length and pump powers for U-type resonator. We obtained green light at 532 nm using a single KTP crystal with average output power of 142W and 127ns pulse duration at 10kHz repetition rate. Also by replacing single LBO crystal with KTP, average output power of 111W with 100ns pulse duration at 10 kHz repetition rate is achieved. Optical-optical efficiency for KTP and LBO crystal was 81.6% and 63.8%, respectively.
