Optical materials for high power yag
WebThe master-oscillator-power-amplifier (MOPA) Nd:YAG laser system has an average power of 100 W and about 1.2 diffraction-limited beam quality. It is Q-switched and/or modelocked. Hence pulse lengths are in the hundreds of picoseconds to hundreds of nanoseconds range, resulting in beam intensities of 10 8 - 10 9 W/cm 2. WebAbstract An investigation of thermal effects in a high-power Nd:YAG disk-type solid state laser pumped with different pump beam transverse profiles is carried out by numerical simulation based on the finite element method (FEM). Impact of the heat sink on the thermal effects is included in the simulation. The distribution of first principle stress, thermally …
