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 …
WebWhite-light diodes (WLEDs) are widely used in high-brightness applications owing to their outstanding advantages. However, current methods for preparing commercial WLEDs significantly deteriorate its optical properties and limits its use in high-power applications. To address this, inorganic materials, such
Neodymium-doped YAG (Nd:YAG) was developed in the early 1960s, and the first working Nd:YAG laser was invented in 1964. Neodymium-YAG is the most widely used active laser medium in solid-state lasers, being used for everything from low-power continuous-wave lasers to high-power Q-switched (pulsed) lasers with power levels measured in the kilowatts.
